Robert Phillips 7eeb74fdfd Add checks that the GrResourceAllocator is operating as expected
With explicit resource allocation there should be no explicit instantiating at flush time. There are, however, still several instances where instantiate is called outside of testing (e.g., readSurfacePixels and writeSurfacePixels).
