mtklein 2c7f24093a Revert of skcpu: sse4.1 floor, f16c f16<->f32 (patchset #11 id:200001 of https://codereview.chromium.org/1891513002/ ) 
Reason for revert:
this depends on a CL I want to revert

Original issue's description:
> skcpu: sse4.1 floor, f16c f16<->f32
>
>   -  floor with roundps is about 4.5x faster when available
>   -  f16 srcover_n is similar to but a little faster than the version in https://codereview.chromium.org/1884683002.  This new one fuses the dst load/stores into the f16<->f32 conversions:

> If we decide to land this it'd be a good idea to convert most or all users of SkFloatToHalf_01 and SkHalfToFloat_01 over to the pointer-based versions.
