-Fast bot fixes for AVX+ code

  1) Replace a couple commas with semicolons.
  2) Make sure to zero a couple vectors.

1) has no effect on code generation.
2) does add a bunch of self-vxorps, but they're cheap and we already do
the equivalent for <AVX SSE code, and they're in not very
performance-critical routines.  We could circle back and guard these
with !defined(JUMPER_IS_OFFLINE) if we really need the vectors to start
uninitialized for speed.
