* match.pd: Add tcc_comparison, inverted_tcc_comparison
and inverted_tcc_comparison_with_nans operator lists.
Use tcc_comparison in the truth_valued_p predicate definition.
Restrict logical_inverted_value with bit_xor to integral types.
Build a boolean true for simplifying x |^ !x because of
vector types. Implement patterns from forward_propagate_comparison
* tree-ssa-forwprop.c (forward_propagate_comparison): Remove.
(get_prop_dest_stmt): Likewise.
(pass_forwprop::execute): Do not call it.
* fold-const.c (fold_unary_loc): Remove the pattern here.
* gcc.dg/tree-ssa/forwprop-28.c: Adjust.
