0e54309477 Merge GrStrokePatchBuilder into GrStrokeTessellateOp
There's really no reason for these classes to be separate at this
point. Also extracts a "GrStrokeOp" base class that has the
functionality that will be shared with indirect stroking.

2882e70ef3 Add GrPathUtils::findCubicConvex180Chops
This method finds the locations a cubic needs to be chopped at before
it can be passed to the stroke tessellation shader. It's an integral
part of CPU stroke preparation and therefore extremely perf sensitive.

83c38a8fd6 Allow uniqueKey invalidation messages to reach the thread safe cache
With the addition of vertex data to the thread safe cache we also have
to handle the case where a given SkPath becomes inaccessible and
proactively invalidate the matching entry.

58a26a8362 Fix the formula for fNumRadialSegmentsPerRadian in GrStrokePatchBuilder
GrStrokePatchBuilder had the wrong formula. This CL moves the formula to
GrStrokeTessellateOp and calculates it in one spot for the builder and
tessellator both. It also fixes a bug that was hiding behind this
formula error and updates some variable names.

e74cebefde Begin implementing onPrePrepare for tessellation ops
Records programInfos for the stroke ops and for the stencil portions
of the path ops.

We can't prePrepare programInfos for the fill portions yet because it
would require multiple GrPipelines that all reference the same
GrProcessorSet. And GrProcessorSet is currently designed to be
std::moved into one single GrPipeline.

e2067645ef Optimize GrWangsFormula
Adds various optimizations to GrWangsFormula as well as "pow4" variants
of the formula that are quicker than the standard and/or log2 versions.
Uses the pow4 variants in GrStrokePatchBuilder.

d358cbebd4 Add support for plumbing GrDstSampleType through Ops and Pipeline creation.
This CL adds a new type GrDstSampleType to say how we will sample the dst.

We add tracking of the GrDstSampleType in the recording of GrOps and
then during execution passing the information along to the GrPipeline.

In general the tracking of GrDstSampleType is a global state of a GrOpsTask
so it is kept separate fro the DstProxyView which is more specific to a
single Op on the GrOpsTask.

5edf510941 Add plumbing for access to the flush-time GrSmallPathAtlasMgr
This isn't connected to anything yet and parallels what is done
for the text GrAtlasManager.

The rough pattern is that the GrContext hierarchy implements creating
the atlas but it is only exposed/made available via the flush state
(which derives from GrDrawMeshOp::Target).

6e2c56fefc move SkArenaAlloc reset to its own class
SkArenaAlloc has three fields that are used only for reset. Make a
subclass called SkArenaAllocWithReset which has the three
fields, and has the reset functionality.

An example of a reset() that is used instead of using a better scope
is PathOpsAngleAfter in PathOpsAngleTest.cpp.
