Updates the handling of perspective quads to calculate the correct,
degenerate-safe projected quad and then derive from that the proper
perspective quad.
In 2D, updated to determine if the optimized outset/inset procedure
is valid, and if not goes through a more robust procedure that is
based on line equation intersections. In particular, the degenerate
inset/outset approach is used when the quad has a zero-length edge,
if insetting/outsetting normally would create a self-intersecting shape,
or if near parallel edge angles would create numerical instabilities.
Performance testing by forcing all rectangle draws through the degenerate
code path suggests that it is about 10% slower than the optimal approach,
at least on my workstation...

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.

We now have a real fuzzer, and these samples only run on local dev
machine anyway, so their current utility is quite low since they don't

GrBuffer is a base class for GrGpuBuffer and GrCpuBuffer. GrGpuBuffer is a
GrGpuResource and the others are not. This allows GrCpuBuffers to exist
outside of the GrGpuResourceCache.
Also removes flags from GrResourceProvider buffer factory function. The
only flag still in use was kRequireGpuMemory. Now CPU buffers are made
without using GrResourceProvider.

GrRenderTargetOpList maintains an array of op chains. When it receives a
new op it tries to add it to an existing chain, working backwards from
the end of the current array. If the op can be added to a chain it
additionally tries to merge the new op with ops already in the chain
before adding it to the tail of the chain.
In forward combining it tries to concatenate chains. If chains can
concatenate it also attempts to merge ops between the two chains.
Now op chaining results reported by Op subclasses must be transitive.
Moreover, if op A is able to merge with B then it must be the case that
any op that can chain with A will either merge or chain with any op that
can chain to B.
