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.
