Some lowp refactoring
1) Move a couple stages around in the enum to places
that make more sense, and guass_a_to_rbga in the code too.
2) mirror the SkRasterPipeline stage enum with either:
LOWP(st): the stage is implemented in low precision
TODO(st): the stage should be lowp, but isn't
NOPE(st): the stage shouldn't be done in lowp.
3) statically enforce that all stages are covered by one of
LOWP, TODO, or NOPE.
