This reverts commit 08a39c2b5f.
Reason for revert: Flutter roll?
Original change's description:
> 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.)
