grand unifried lowp stages
I have text_16_AA_FF -> 8888 (forcing RP) faster than head now on my
laptop. I'm feeling confident that we can make this perform well.
After looking at performance a bit more today, it looks like everything
is within what I'd consider comparable in performance, especially on
ARM. On x86-64 it looks like big bulk blits get a little slower and
small mask blits get a little faster.
Quality looks good, and maybe improved for 565.
There are fewer platform-specific differences now in _lowp, and I think
they're few enough now that we could even consider completing the
unification by folding the 8-bit and float code together. Rename
"div255()" to "rebias()", slap on a few coats of paint...
Guarded for Chrome with SK_JUMPER_LEGACY_LOWP.
