AVX 2 SrcOver blits: color32, blitmask.
As a follow up to the SSE 4.1 CL, this should look pretty familiar.
I've made some organizational changes around how we load, store, pack, and unpack data that I think makes things clearer and more orthogonal, and it'll make it easier to try out a pmaddubsw lerp. I have backported these changes to the SSE 4.1 code, and I hope that I can actually get a lot of this code templated for sharing between the two later.
Perf changes (relative to SSE 4.1):
Xfermode_SrcOver: 1650 -> 1180 (0.71x) // large opaque blit
Xfermode_SrcOver_aa: 1794 -> 1653 (0.92x) // large opaque + small transparent
text_16_AA_{FF,BK,WT}: 1.72 -> 1.59 (0.92x) // small opaque blit
text_16_AA_88: 1.83 -> 1.77 (0.97x) // small transparent blit
This should be a big throughout win, and a small latency win.
This should all be pixel-exact to the previous SSE 4.1 code.
