Original change's description:
> GrTessellator (AA): Performance tweaks and cleanup.
> 
> The SkArenaAlloc destructor was showing up as hot in profiling,
> especially on Linux.  The reason is that it was being used
> incorrectly: the size estimate was being used as the chunk size. It
> turns out that the best performance seems to be achieved with no
> initial allocations and a fixed chunk size of 16K, as the CPU path
> renderer does.
> 
> Also, allocate the bisectors used for edge inversions on the
> stack, not the heap. And remove some unused code.
