Reland "standardize macro checks in SkRasterPipeline_opts"

Browse Source 
This is a reland of 75d25c4c8f

Last time I screwed up by replacing defined(__AVX2__) with
defined(JUMPER_IS_HSW).  When __AVX2__ is defined, we'll
be using AVX2, _or better_.

This time around I think I've got it all straight
translating the old __FOO__ into the equivalent JUMPER_IS_FOO.

Last time I also missed a defined(__SSE__), which has been
translated into JUMPER_IS_FOOs now too.

Original change's description:
> standardize macro checks in SkRasterPipeline_opts
>
> We mostly check JUMPER_IS_FOO macros, but in a few places we are
> checking the raw __FOO__ compiler macros instead.  If only for clarity,
> switch to JUMPER_IS_FOO.
>
> This is also a step towards me being able to control the instruction
> set we choose without having to #define these protected __FOO__ macros.
