add Min to SkNi, specialized for u8 and u16 on SSE and NEON
0x8001 / 0x7fff don't seem to work, but we were close: 0x8000 does.
I plan to use this to implement the Difference xfermode,
and it seems generally handy.

Split rsqrt into rsqrt{0,1,2}, with increasing cost and precision on ARM
This is a logical no-op. Everything was using the equivalent of rsqrt1() before, and is now after.

Mike's radial gradient CL with better float -> int.
patch from issue 1072303005 at patchset 40001 (http://crrev.com/1072303005#ps40001)
This looks quite launchable. radial_gradient3, min of 100 samples:
N5: 985µs -> 946µs
MBP: 395µs -> 279µs
On my MBP, most of the meat looks like it's now in reading the cache and writing to dst one color at a time. Is that something we could do in float math rather than with a lookup table?

Sk4h and Sk8h for SSE
These will underly the SkPMFloat-like class for uint16_t components.
Sk4h will back a single-pixel version, and Sk8h any larger number than that.

Use switch operator[](int) to kth<int>() so we can use vget_lane.

Refactor Sk2x<T> + Sk4x<T> into SkNf<N,T> and SkNi<N,T>
The primary feature this delivers is SkNf and SkNd for arbitrary power-of-two N. Non-specialized types or types larger than 128 bits should now Just Work (and we can drop in a specialization to make them faster). Sk4s is now just a typedef for SkNf<4, SkScalar>; Sk4d is SkNf<4, double>, Sk2f SkNf<2, float>, etc.
This also makes implementing new specializations easier and more encapsulated. We're now using template specialization, which means the specialized versions don't have to leak out so much from SkNx_sse.h and SkNx_neon.h.
This design leaves us room to grow up, e.g to SkNf<8, SkScalar> == Sk8s, and to grown down too, to things like SkNi<8, uint16_t> == Sk8h.
To simplify things, I've stripped away most APIs (swizzles, casts, reinterpret_casts) that no one's using yet. I will happily add them back if they seem useful.
You shouldn't feel bad about using any of the typedef Sk4s, Sk4f, Sk4d, Sk2s, Sk2f, Sk2d, Sk4i, etc. Here's how you should feel:
- Sk4f, Sk4s, Sk2d: feel awesome
- Sk2f, Sk2s, Sk4d: feel pretty good
No public API changes.
