Merge joins into the same tessellation patch as their following stroke
Implements the previous join as a sub-section of the tessellation
patch. This cuts the number of vertex shader invocations in half since
we are no longer treating joins as their own patch. (This therefore
cuts the amount of inflection/midtangent chopping work in half also.)
This required a lot of modifications to GrStrokePatchBuilder.cpp, so
this CL also finishes up the chopping logic in that file for when there
aren't enough tessellation segments to render a curve.
