- Change the multiply with overflow so that we distinguish between signed and
  unsigned multiplication. Currently, unsigned multiplication with overflow
  isn't working!

Added PTH optimization to not process entire blocks of tokens that appear in skipped preprocessor blocks.  This improves PTH speed by 6%.  The code for this optimization itself is not very optimized, and will get cleaned up.

Substantially improve error recovery after broken if conditions by
parsing the full if when we have a semantic error instead of using
parser recovery techniques to recover from a semantic error.
