abandon SK_IGNORE_TREAT_AS_SPRITE as a flag, and use SK_IGNORE_TRANS_CLAMP_FIX
for the fixes in SkDraw.cpp and SkBitmapProcState.cpp

Also, change the call in SkDraw.cpp to pass 0 for subpixel bits, to match the
old logic.... we should have a runtime fix for this in the future, so a caller
*can* get subpixel-filtered images w/ just translate.
