Chris Dalton b8fff0dfce Make mixed samples detection automatic
Previously, we relied on ops to deduce whether a draw would have
hardware coverage modulation as a result mixed samples. This is
problematic because *any* draw can have mixed samples coverage if
there is a multisampled stencil clip. No ops were checking for stencil
clip, and most just said they never used mixed samples.

Now that the only usecase for mixed samples is the stencil buffer,
this CL makes the processorSet automatically deduce mixed samples
coverage from the stencil settings and fsaaType.
