Assembly optimized 4 blittering related functions:

S32A_D565_Opaque
S32A_Opaque_BlitRow32
nofilter_gether
S32A_Blend_BlitRow32

* S32A_D565_Opaque:

Use neon instructions to optimize BLIT routine which operates on
32-bit source ARGB pixel and 16-bit destination RGB pixel. Here,
we process 16-pixels in an iteration. We use regular (32-bit)
arm instructions when number of pixels is less than 16 or the
architecture doesn't support SIMD/NEON instructions. When alpha
value is 255, this version of BLIT routine performs 35% better
in comparison to S32A_D565_Opaque_neon routine.

* S32A_Opaque_BlitRow32 and nofilter_gether:

Use neon instructions to optimize BlitRow32 and nofilter_gether
functions for 32-bit source and destination pixel arrays. An improvement
of 76% is observed with neon optimized BlitRow32 function and 6%
improvement is observed with nofilter_gether function.

* S32A_Blend_BlitRow32:

Optimize S32A_Blend_BlitRow32 using neon instructions for armv7
based targets and using regular arm instructions for armv6 based
targets.

This is the consolidated commit from several patches.

Two skia optimizations:

1. Combine S16_opaque_D32_nofilter_DX and clampx_nofilter_trans
2. Change MAX_BUF between mproc and sproc to 1024 from 128

Opt 1 is giving about 8-10 FPS in gmail and facebook apk.
Opt 2 is helping all combinations for shaderspan.

skia_bench: fix crash due to memory issue

currently the BenchTimer.cpp is pulling in the class
definintions for its underlying timers from BenchSysTimer_c.[h/c].

However, the Android.mk links it with BenchSysTimer_posix.c. This
is causing a crash when the destructor calls delete on the object.

This patch ensures that we pull in the header required by Android.mk.

NOTE: simply defining SK_BUILD_FOR_UNIX does not work because that
causes other parts of skia_bench to using things link GL that we don't
have access to in an android build.

skia: Fix a bug in clampx_nofilter_trans_S16_D32_DX

When scaling a line, in the case of the last pixel needing to be
duplicated, the beginning of the line is getting clobbered with wrong
value.  This is because dest buffer pointer is not moved forward.  Fix
that by adding pointer update line.
