Intialize memory to zero to silence MSan.

The MemorySanitizer tool can't instrument JIT-compiled code, so it's
unaware that the vertex processing routine writes the clip flags before
they're being read by triangle setup. This false positive can be
silenced by zeroing the memory at allocation. For good measure, zero
out all intermediate buffers.
