tree-optimization/110491 - PHI-OPT and undefs
The following makes sure to not make conditional undefs in PHI arguments
unconditional by folding cond ? arg1 : arg2.
PR tree-optimization/110491
* tree-ssa-phiopt.cc (match_simplify_replacement): Check
whether the PHI args are possibly undefined before folding
the COND_EXPR.
* gcc.dg/torture/pr110491.c: New testcase.
