Simplify more: remove SkRasterPipeline::compile().
It's easier to work on SkJumper if everything funnels through run().
I don't anticipate huge benefit from compile() without JITing,
but it's something we can always put back if we find a need.

Remove SkTextureCompressor.
This is the ultimate state of what it looks like to remove
SkTextureCompressor.
This end result will result from the following steps.
1) Remove Skia dep on ktx (done)
2) Move format over to ktx (done)
3) Remove all SkTexture compressor code

SkRasterPipeline::compile().
I'm not yet caching these in the blitter, and speed is essentially unchanged in the bench where I am now building and compiling the pipeline only once. This may not be able to stay a simple std::function after I figure out caching, but for now it's a nice fit.

Move SkRasterPipeline further into SkOpts.
The portable code now becomes entirely focused on enum+ptr descriptions, leaving the concrete implementation of the pipeline to SkOpts::run_pipeline().
As implemented, the concrete implementation is basically the same, with a little more type safety.
Speed is essentially unchanged on my laptop, and that's having run_pipeline() rebuild its concrete state every call. There's room for improvement there if we split this into a compile_pipeline() / run_pipeline() sort of thing, which is my next planned CL.

SkRasterPipeline refactor
- Give body and tail functions separate types. This frees a register in body functions, especially important for Windows.
- Fill out default, SSE4.1, and HSW versions of all functions. This means we don't have to mess around with SkNf_abi... all functions come from the same compilation unit where SkNf is a single consistent type.
- Move Stage::next() into SkRasterPipeline_opts.h as a static inline function.
- Remove Stage::ctx() entirely... fCtx is literally the same thing.
This is a step along the way toward building the entire pipeline in src/opts, removing the need for all the stages to be functions living in SkOpts.

Add SkRasterPipeline support to SkModeColorFilter.
The shader leaves its color in r,g,b,a, so to implement this color filter, we move {r,g,b,a} into {dr,dg,db,da}, then load the filter's color in {r,g,b,a}, then apply the xfermode as usual.
I've left a note about how we could sometimes cut a stage for some xfermodes. Similarly we really only need to move_src_dst instead of swap_src_dst, but it seemed handy and less error prone to do a full two way swap. As usual, we can always circle back and fine-tune these things if we want.

SkRasterPipeline: 8x pipelines, attempt 2
Original review here: https://skia-review.googlesource.com/c/2990/
Changes since:
- simpler implementations of load_tail() / store_tail(): slower, but more obviously correct to all compilers
- fleshed out math ops on Sk8i and Sk8u to make unit tests happy on -Fast bot (where we always have AVX2)
- now storing stage functions as void(*)() to avoid undefined behavior and/or linker problems. This restores 32-bit Windows.
- all AVX2 Sk8x methods are marked always-inline, to avoid linking the "wrong" version on Debug builds.

SkRasterPipeline: 8x pipelines
Bench runtime changes:
sRGB: 7194 -> 3735 = 1.93x faster
F16: 6531 -> 2559 = 2.55x faster
Instead of building 4x and 1-3x pipelines and then maybe 8x and 1-7x, instead build either the short ones or the long ones, but not both. If we just take care to use a compatible run_pipeline(), there's some cross-module type disagreement but everything works out in the end.
Oddly, a few places that looked like they'd be faster using SkNx_fma() or Sk4f_round()/Sk8f_round() are actually faster the long way, e.g. multiply, add 0.5, truncate. Curious! In all the other places you see here that I've used SkNx_fma(), it's been a significant speedup.
This folds in a couple refactors and cleanups that I've been meaning to do. Hope you don't mind... if find the new code considerably easier to read than the old code.

Make all SkRasterPipeline stages stock stages in SkOpts.
If we want to support VEX-encoded instructions (AVX, F16C, etc.) without a ridiculous slowdown, we need to make sure we're running either all VEX-encoded instructions or all non-VEX-encoded instructions. That means we cannot mix arbitrary user-defined SkRasterPipeline::Fn (never VEX) with those living in SkOpts (maybe VEX)... it's SkOpts or bust.
This ports the existing user-defined SkRasterPipeline::Fn use cases over to use stock stages from SkOpts. I rewrote the unit test to use stock stages, and moved the SkXfermode implementations to SkOpts. The code deleted for SkArithmeticMode_scalar should already be dead.

Add an SkOpts target for Haswell+ Intel chips.
Haswell brought a whole slew of handy new instructions for us (AVX2, FMA, BMI1+BMI2) and also feature F16C, which came one generation earlier on Ivybridge. We work with integers often enough that we really want to target AVX2 instead of AVX, and this means it's pretty practical to ask for all those other goodies along with it.
Chrome's GN files and Google3's BUILD file will need an update, before or after this CL.

Add an enum layer of indirection for stock raster pipeline stages.
This is handy now, and becomes necessary with fancier backends:
- most code can't speak the type of AVX pipeline stages,
so indirection's definitely needed there;
- if the pipleine is entirely composed of stock stages,
these enum values become an abstract recipe that can be JITted.

Start moving SkRasterPipeline stages to SkOpts.
This lets them pick up runtime CPU specializations. Here I've plugged in SSE4.1. This is still one of the N prelude CLs to full 8-at-a-time AVX.
I've moved the union of the stages used by SkRasterPipelineBench and SkRasterPipelineBlitter to SkOpts... they'll all be used by the blitter eventually. Picking up SSE4.1 specialization here (even still just 4 pixels at a time) is a significant speedup, especially to store_srgb(), so much that it's no longer really interesting to compare against the fused-but-default-instruction-set version in the bench. So that's gone now.
That left the SkRasterPipeline unit test as the only other user of the EasyFn simplified interface to SkRasterPipeline. So I converted that back down to the bare-metal interface, and EasyFn and its friends became SkRasterPipeline_opts.h exclusive abbreviations (now called Kernel_Sk4f). This isn't really unexpected: SkXfermode also wanted to build up its own little abstractions, and once you build your own abstraction, the value of an additional EasyFn-like layer plummets to negative.
For simplicity I've left the SkXfermode stages alone, except srcover() which was always part of the blitter. No particular reason except keeping the churn down while I hack. These _can_ be in SkOpts, but don't have to be until we go 8-at-a-time.

Use ARMv8 CRC32 instructions for SkOpts::hash().
For large inputs, this runs ~11x faster than Murmur3.
My bench drops from 1µs to 88ns.
Like x86-64, this runs fastest if we work in 24 byte chunks. 16 byte chunks
run at about 0.75x this speed, 8 byte chunks at about 0.4x (which would still
be about 5x faster than Murmur3).
This'll require plumbing support for opts_crc32 into Chrome first before it can roll.

Refactor of SkColorSpaceXformOpts
(1) Performance is better or stays the same.
(2) Code is split into functions (RasterPipeline-ish
design). IMO, it's not really more or less readable.
But I think it's now much easier add capabilities,
apply optimizations, or do more refactors. Or to
actually use RasterPipeline. I help back from trying
any of these to try to keep this CL sane.

Update SkOpts namespaces.
If we make sure all SkOpts functions are static, we can give the namespaces any
name we like. This lets us drop the sk_ prefix and give a real indication of
the default SIMD instruction set rather than just saying sk_default.
Both of these changes help debugger, profiler, and crash report readability.
Perhaps more importantly, keeping these functions static helps prevent
accidentally linking in unused versions of functions, as you see here with
sk_avx::srcover_srgb_srgb().
This requires we update SkBlend_opts tests and benches to call SkOpts functions
through SkOpts rather than declaring the methods externally. In practice this
drops testing of the SSE2 version on machines with SSE4. If we still really
need to test/bench the compile time best SIMD level version of this method
against the runtime detected best, we can include SkBlend_opts.h into the tests
or benches directly, similar to what we do for the trivial, brute-force, or best
non-SIMD versions.

Optimize color xforms with 2.2 gammas for SSE2
Because we recognize commonly used gamma tables and
parameters as 2.2f, about 98% of jpegs with color profiles
will pass through this xform (assuming the dst is also
2.2f). Sample size is 10,322 jpegs.
I won't go crazy with performance numbers because this is
a work in progress, particularly in terms of correctness.
201295.jpg on HP z620
(300x280, most common form of sRGB profile)
Decode Time + QCMS Xform 1.28 ms
QCMS Xform Only 0.495 ms
Decode Time + Skia Opt Xform 1.01 ms
Skia Opt Xform Only 0.235 ms
Decode Time + Xform Speed-up 1.27x
Xform Only Speed-up 2.11x
FWIW, Skia xform time before these optimizations was
41.1 ms. But we expected that code to be slow.

[GN] Add support for disabling opts via SK_BUILD_NO_OPTS define.
When targetting iOS and using gyp to generate the build files, it is not
possible to select files to build depending on the architecture. Due to
that, the skia code was disabling all optimisation when SK_BUILD_FOR_IOS
was defined.
Since it is possible to select the correct optimised version when using
gn, this pessimisation is hurting the build. Introduce a new define to
disable the optimisation SK_BUILD_NO_OPTS. It will be used by Chromium
when building skia for iOS with gyp but not gn.
Define SK_BUILD_NO_OPTS along-side SK_BUILD_FOR_IOS for all files that
look like build configuration (Xcode projects, gyp configuration files,
public.bzl) in order to avoid introducing breakage on those builds.

Add a hook for CPU-optimized sRGB-sRGB srcover.
Herb's really starting to get serious about tweaking this, which becomes
a lot easier when you've got SkOpts' runtime CPU detection. We should be
able to optimize this usefully for SSSE3, SSE4.1, AVX, AVX2, or NEON.
(We can of course implement a subset.)
This function takes two counts to give us flexibility to write src patterns:
nsrc >= ndst -> the usual srcover function
nsrc < ndst -> repeat src until it fills dst
nsrc << ndst -> possibly preprocess src into registers
nsrc == 1 -> equivalent of blitrow_color32, srcover_1, etc.

Move CPU feature detection to its own file.
- Moves CPU feature detection to its own file.
- Cleans up some redundant feature detection scattered around core/ and opts/.
- Can now detect a few new CPU features:
* F16C -> Intel f16<->f32 instructions, added between AVX and AVX2
* FMA -> Intel FMA instructions, added at the same time as AVX2
* VFP_FP16 -> ARM f16<->f32 instructions, quite common
* NEON_FMA -> ARM FMA instructions, also quite common
* SSE and SSE3... why not?
This new internal API makes it very cheap to do fine-grained runtime CPU
feature detection. Redundant calls to SkCpu::Supports() should be eliminated
and it's hoistable out of loops. It compiles away entirely when we have the
appropriate instructions available at compile time.
This means we can call it to guard even a little snippet of 1 or 2 instructions
right where needed and let inlining hoist the check (if any at all) up to
somewhere that doesn't hurt performance. I've explained how I made this work
in the private section of the new header.
Once this lands and bakes a bit, I'll start following up with CLs to use it more
and to add a bunch of those little 1-2 instruction snippets we've been wanting,
e.g. cvtps2ph, cvtph2ps, ptest, pmulld, pmovzxbd, blendvps, pshufb, roundps
(for floor) on x86, and vcvt.f32.f16, vcvt.f16.f32 on ARM.

Remove static initializer for SkOpts::Init()
Static initializers run in a confusing unspecified order,
so it's best to have as few of them as possible.
Most tools and clients I can find already call SkGraphics::Init(),
(or equivalently create an SkAutoGraphics) which calls SkOpts::Init():
- Chrome
- Chrome renderer
- Android
- DM
- nanobench
- SampleApp
- VisualBench
- the old debugger
Seems like the only thing relying on this static initializer today is
the new debugger, fixed here.

Modernize and trim down SkOnce.
The API and implementation are very much simplified.
You may not want to bother reading the diff.
As is our trend, SkOnce now uses <atomic> directly.
Member initialization means we don't need SK_DECLARE_STATIC_ONCE.
SkSpinlock already works this same way.
All uses of the old API taking an external bool* and Lock* were pessimal,
so I have not carried this sort of API forward. It's simpler, faster,
and more space-efficient to always use this single SkOnce class interface.
SkOnce weighs 2 bytes: a done bool and an SkSpinlock, also a bool internally.
This API refactoring opens up the opportunity to fuse those into a single
three-state byte if we'd like.
No public API changes.

skeleton for float <-> half optimized procs
Nothing fancy yet, just calls the serial code in a loop.
I will try to folow this up with at least some of:
- SSE2 version of serial code
- NEON version of serial code
- NEON version using vcvt.f32.f16/vcvt.f16.f32
- F16C (between AVX and AVX2) version using vcvtph2ps/vcvtps2ph
The last two are fastest but need runtime detection.

Refactor swizzle names and types.
- Plant a flag to say "pretend all the inputs are RGBA".
This is how libpng thinks.
This is the opposite of what the implementation had been doing,
so I've rearranged everything to reflect the new orientation.
- Rewrite the names to be less mysterious looking. No more Xs.
- Make the src type uniformly const void*, to allow for 888 (RGB) srcs.
This should be performance and pixel neutral. (Please revert if it's not.)

Optimized premultiplying swizzles for NEON
Improves decode performance for RGBA encoded PNGs.
Swizzle Time on Nexus 9 (with clang):
SwapPremul 0.44x
Premul 0.44x
Decode Time On Nexus 9 (with clang):
ZeroInit Decodes 0.85x
Regular Decodes 0.86x
Swizzle Time on Nexus 6P (with clang)
SwapPremul 0.14x
Premul 0.14x
Decode Time On Nexus 6P (with clang):
ZeroInit Decodes 0.93x
Regular Decodes 0.95x
Notes:
ZeroInit means memory is zero initialized, and we do not write to
memory for large sections of zero pixels (memory use opt for Android).
A profile on Nexus 9 shows that the premultiplication step of PNG
decoding is now ~5% of decode time (down from ~20%).

Set up some hooks for premul/swizzzle opts.
You can call these as SkOpts::premul_xxxa, SkOpts::swaprb_xxxa, etc.
For now, I just backed the function pointers with some (untested) portable
code, which may autovectorize. We can override with optimized versions in
Init_ssse3() (in SkOpts_ssse3.cpp), Init_neon() (SkOpts_neon.cpp), etc.

Incidental stuff:
I made the SkNx(T) constructors implicit to make writing math expressions simpler.
This allows us to write expressions like
Sk4f v;
...
v = v*4;
rather than
Sk4f v;
...
v = v * Sk4f(4);
As written it only works when the constant is on the right-hand side,
so expressions like `(Sk4f(1) - da)` have to stay for now. I plan on
following up with a CL that lets those become `(1 - da)` too.

Port SkMatrix opts to SkOpts.
No changes to the code, just moved around.
This will have the effect of enabling vectorized code on ARMv7.
Should be no effect on ARMv8 or x86, which would have been vectorized already.
nanobench --match mappoints changes on Nexus 5 (ARMv7):
_affine: 132 -> 95
_scale: 118 -> 47
_trans: 60 -> 37
A teaser:
We should next look at the ABCD->BADC shuffle we've noted that we need in _affine. A quick hack showed doing that optimally is another ~35% speedup on x86. Got to figure out how to do it best on ARM though: that same quick hack was a 2x slowdown there. Good reason to resurrect that SkNx_shuffle() CL!
(I believe the answers are vrev64q_f32(v) and _mm_shuffle_ps(v,v, _MM_SHUFFLE(2,3,0,1), but we should probably find out in another CL.)

Remove SkOpts_sse2.cpp.
It's sort of pointless: all our clients that will have SSE2 at runtime have it
unconditionally at compile time, so the functions in namespace portable will
pick up the SSE2 code. The procs in SkOpts_sse2.o were just duplicate code.
A couple of the procs we had in _sse2.cpp can benefit slightly when compiled
with SSSE3. I've moved those to _ssse3.cpp. This should lead to small speedups
on platforms like Linux and Windows that have a baseline of SSE2.
Similarly, I've removed the call to Init_neon() when NEON is available globally... it's a no-op.
Renaming namespace portable to something clearer is TBD.

Refactor to put SkXfermode_opts inside SK_OPTS_NS.
Without this refactor I was getting warnings previously about having code
inside namespace SK_OPTS_NS (e.g. namespace sse2, namespace neon) referring to
code inside an anonymous namespace (Sk4px, SkPMFloat, Sk4f, etc) [1].
That low-level code was in an anonymous namespace to allow multiple independent
copies of its methods to be instantiated without the linker getting confused /
offended about violating the One Definition Rule. This was only happening in
Debug mode where the methods were not being inlined.
To fix this all, I've force-inlined the methods of the low-level code and
removed the anonymous namespace.

Sk4px blit mask.
Local SKP nanobenching ranges SSE between 1.05x and 0.87x, much more heavily weighted toward <1.0x ratios (speedups).
I profiled the top five regressions (1.05x-1.01x) and they look like noise. Will follow up after broad bot results.
NEON looks similar but less extreme than SSE changes, ranging between 1.02x and 0.95x, again mostly speedups in 0.99x-0.97x range.
The old code trifurcated into black, opaque-but-not-black, and general versions as a function of the constant src color. I did not see a significant difference between general and opaque-but-not-black, and I don't think a black version would be faster using SIMD. So we have here just one version of the code, the general version.
Somewhat fantastically, I see no pixel diffs on GMs or SKPs.
I will be following up with more CLs for the other procs called by SkBlitMask.

Port SkTextureCompression opts to SkOpts
Pretty vanilla translation. I cleaned up who calls whom a little.
Used to be utils -> opts -> utils, now it's just utils -> opts.
I may follow up with a pass over the NEON code for readability
and to clean up dead code.
This turns on NEON A8->R11EAC conversion for ARMv8.
Unit tests which now hit the NEON code still pass.
I can't find any related bench.

Port morphology to SkOpts.
Nothing too fancy.
Direction enums become enum classes so they don't get all confused. An
alternative is to create one single Direction enum that both blur and
morphology opts use.

Reorganize to keep similar code together.
This organizes memset16, memset32, and rsqrt the same way as the other code. No functional change.

Port SkBlurImage opts to SkOpts.
+268 -535 lines
I also rearranged the code a little bit to encapsulate itself better,
mostly replacing static helper functions with lambdas. This also
let me merge the SSE2 and SSE4.1 code paths.

Port SkXfermode opts to SkOpts.h
Renames Sk4pxXfermode.h to SkXfermode_opts.h,
and refactors it a tiny bit internally.
This moves xfermode optimization from being "compile-time everywhere but NEON"
to simply "runtime everywhere". I don't anticipate any effect on perf or
correctness.

Port SkUtils opts to SkOpts.
With this new arrangement, the benefits of inlining sk_memset16/32 have changed.
On x86, they're not significantly different, except for small N<=10 where the inlined code is significantly slower.
On ARMv7 with NEON, our custom code is still significantly faster for N>10 (up to 2x faster). For small N<=10 inlining is still significantly faster.
On ARMv7 without NEON, our custom code is still ridiculously faster (up to 10x) than inlining for N>10, though for small N<=10 inlining is still a little faster.
We were not using the NEON memset16 and memset32 procs on ARMv8. At first blush, that seems to be an oversight, but if so it's an extremely lucky one. The ARMv8 code generation for our memset16/32 procs is total garbage, leaving those methods ~8x slower than just inlining the memset, using the compiler's autovectorization.
So, no need to inline any more on x86, and still inline for N<=10 on ARMv7. Always inline for ARMv8.

Runtime CPU detection for rsqrt().
This enables the NEON sk_float_rsqrt() code for configurations that have NEON at run-time but not compile-time.
These devices will see about a 2x (1.26 -> 2.33) slowdown in sk_float_rsqrt(), but it should be more precise than our portable fallback.
(When inlined, the portable fallback and the NEON code are almost identical in speed. The only difference is precision. Going through a function pointer is causing all this slowdown. This is a good example of a place where Skia really benefits from compile-time NEON.)

This doesn't really do anything yet. It's just the CPU detection code, skeleton new .cpp files, and a few little .gyp tweaks.
