Try inverted comparison for match_simplify in phiopt
Since match and simplify does not have all of the inverted
comparison patterns, it make sense to just have
phi-opt try to do the inversion and try match and simplify again.
OK? Bootstrapped and tested on x86_64-linux-gnu.
Thanks,
Andrew Pinski
gcc/ChangeLog:
* tree-ssa-phiopt.c (gimple_simplify_phiopt):
If "A ? B : C" fails to simplify, try "(!A) ? C : B".
