Make gMask_00FF00FF a constant
This is to optimize SkAlphaMulQ() in PIC mode. With the visibility=default
symbol the constant is not known at compile time (and is not a constant), but
instead is fetched through a double indirection through GOT. The function is
quite hot on one of the chromium benchmarks:
rasterize_and_record_micro.key_silk_cases.
This change replaces the symbol with a compile-time constant. As a bonus the
variable is not exported from the dynamic library, i. e. a cleaner library
interface.

Xfermode: SSE2 implementation of overlay_modeproc
With SSE2 optimization, performance of Xfermode_Overlay will improve
about 35% on desktop i7-3770. Here are the data:
before:
Xfermode_Overlay 8888: cmsecs = 44.17 565: cmsecs = 59.27
after:
Xfermode_Overlay 8888: cmsecs = 28.30 565: cmsecs = 35.84

Reason for revert:
It looks like serialization is broken. The serialize and pipe-cross-process tests are failing and turning (at least the Ubuntu12 and Win7) bots red
