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.

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.

Draws can specify "fixed dynamic state" which doesn't use the dynamism at
all or can specify dynamic state arrays with an entry per GrMesh.
When we state other than scissor rects this will allow the caller to
use a mix of truly dynamic and fixed dynamic state. So a caller that
only has dynamic scissor rects doesn't need to store its remaining
unvarying state in an array.
