08a39c2b5fd66f8f9e0d4b6e2dd786fa26bfa991 apply SkOpts_skx approach to SkOpts_hsw
Very slightly different build flags, switching from -march=haswell to
-mavx2 -mfma -mf16c, but there are no diffs.
Left some TODOs for the next ones, but _hsw being so common I figured
I'd do this one stand alone and make sure it shakes down before doing
the rest.
clang-cl (but not clang) barfs when we've got a lambda using an AVX
intrinsic inside a templated static helper function. Luckily they're
all non-type template parameters, so we can just pass them as normal
arguments, and it'll optimize the same as the templated code anyway.
This was weird, but since we're covering almost all the SkFoo_opts.h
headers with HSW here, I don't anticipate this being a problem in the
future. (And I'm sure I'll never look back on this statement as naive.)
