add BlitRow procs for 32->32, to allow for neon and other optimizations.
call these new procs in (nearly) all the places we had inlined loops before.
In once instance (blitter_argb32::blitAntiH) we get different results by a
  tiny bit. The new code is more accurate, and exactly inline with all of the
  other like-minded blits, so I think the change is good going forward.
