This series contains simplifications of compaes between a constant
and a constant AND/OR mask.

Luc Van Oostenryck (9):
  change testing of signed compares against SMIN or SMAX
  add testcases for constant compares against AND/OR
  simplify (x & M) cmps C
  simplify (x & M) cmpu C
  simplify (x & M) cmps 0
  simplify (x & M) {==,!=} C
  simplify (x | M) {==,!=} C
  simplify (x | M) cmps C
  simplify (x | M) cmpu C
