henrik.smiding e2527b1476 Add SSE4 optimization of S32A_Opaque_Blitrow 
Adds optimization of Skia S32A_Opaque_Blitrow blitter using SSE4.2 SIMD
instruction set. Special case for when alpha is zero or opaque.

Performance increase of 10%-400% compared to the existing SSE2
optimization (measured on Silvermont architecture).
Noticeable in ~25 different skia bench subtests, especially in
bitmap_8888_*, repeatTile_*, and morph_*.

bitmap_8888_A - 100% faster
bitmap_8888_A_source_transparent - 250% faster
bitmap_8888_A_source_opaque - 25% faster
bitmap_8888_A_scale_bicubic - 75% faster
