SkRasterPipeline: 8x pipelines, attempt 2
Original review here: https://skia-review.googlesource.com/c/2990/
Changes since:
- simpler implementations of load_tail() / store_tail(): slower, but more obviously correct to all compilers
- fleshed out math ops on Sk8i and Sk8u to make unit tests happy on -Fast bot (where we always have AVX2)
- now storing stage functions as void(*)() to avoid undefined behavior and/or linker problems. This restores 32-bit Windows.
- all AVX2 Sk8x methods are marked always-inline, to avoid linking the "wrong" version on Debug builds.
