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.
