ARM Skia NEON patches - 20 - New improved BitmapProcState code
BitmapProcState: new factorised code
This one basically factorises the clamp and repeat transformations with
some performance improvements. It has the benefit of being faster, much
easier to maintain (nearly three times less code for more work
done :-)), and more complete (all persp transformations weren't optimised
in the previous version).
It also introduces the use of can_truncate_to_fixed_for_decal where
useful.
The effect on benchmarks ranges from a 5% penalty to a 25% gain on a
Cortex-A9 and from a 5% penalty to a 100% gain on a Cortex-A15.

ARM Skia NEON patches - 18 - Preparation work for BitmapProcState
BitmapProcState: clean a little and get rid of some asm
replacing the apparently stupid dx+dx+dx leads to more instructions
being generated.

Fix errors when compiling with -Wall -Werror on Android.
This CL also turns those features on by default on Android

arm: dynamic NEON support for SkBitmapProcState matrix operations.
This patch implements dynamic ARM NEON support for the functions
implemented by src/core/SkBitmapProcState_matrixProcs.cpp.
- Because the SkBitmapProcState_matrix_{clamp,repeat}.h headers
are NEON-specific, they are renamed with a _neon.h suffix, and
moved to src/opts/ (from src/core/)
- Add a new file src/opts/SkBitmapProcState_matrixProcs_neon.cpp
which implements the NEON code paths for all builds, and add
it to the 'opts_neon' static library.
- Modify SkBitmapProcState_matrixProcs.cpp to select the right
code-path depending on our build configuration. Note that in
the case where 'arm_neon == 1', we do not embed regular ARM
code paths in the final binary. Only 'arm_neon_optional == 1'
builds will contain both regular and NEON code paths at the
same time.
Note that there doesn't seem to be a simple way to put the
NEON-specific selection from that currently is in
SkBitmapProcState_matrixProcs.cpp into src/opts/. Doing so
would require much more drastic restructuring. This is also
true of the other SkBitmapProcState source files that will
be touched in a future patch.
