Brian Osman 409e74fb2c Further refactor read/writeSurfacePixels 
Detect the situation where we're going to want to do PM/UPM, and want to
use GrConfigConverionEffect, but be unable (due to the lack of a
round-trip pair). This lets us hoist the SW premul work (in
writeSurfacePixels), and avoid all the cascading failure logic in both
functions. (We never try to create the PM/UPM effects unless we know
that they're going to work).
