Original issue's description:
> 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
