Brian Salomon c0b642ca48 Split GrPipelineInput into separate color and coverage types, the latter of which is just an enum. 
Assign names that indicate that they aren't just for the input phase since I plan to use them at the boundary between FPs and XPs as well.

Renamed GrProcOptInfo to GrColorFragmentProcessorAnalysis. This is now only used on the color side and the new name seems clearer to me.

Change GrMeshDrawOp::getFragmentProcessorAnalysisInputs to use the new color/coverage types directly rather than a class that has been reduced to simply bundling them together.
