  SVN rev 191261 on 2009-04-19 06:30:00Z by nwhitehorn
  
  Fix a typo in the SRR1 comparison for program exceptions. While here,
  replace magic numbers with constants to keep this from happening again.
  
  Without this fix, some programs would occasionally get SIGTRAP instead
  of SIGILL on an illegal instruction. This affected Altivec detection
  in pixman, and possibly other software.
