tree-optimization/110269 - restore missed condition folding
The following makes sure we optimize x != 0 using range info
via tree_expr_nonzero_p via match.pd.
PR tree-optimization/110269
* fold-const.cc (fold_binary_loc): Merge x != 0 folding
with tree_expr_nonzero_p ...
* match.pd (cmp (convert? addr@0) integer_zerop): With this
pattern.
* gcc.dg/tree-ssa/pr110269.c: New testcase.
