Allow FPs to elevate default precision for the entire fragment program
Currently, GrConfigConversionEffect is able to round-trip on many mobile
GPUs because it uses highp for all intermediate variables (including the
texture fetch result). Separating the texture sample into a different
processor breaks that.
This is a blunt instrument, not to be used lightly.
