Move "(A & C) == D is false when D & ~C != 0" to match.pd
2017-05-25 Marc Glisse <marc.glisse@inria.fr>
* fold-const.c (fold_binary_loc) [(A & C) == D]: Remove transformation.
* match.pd (X == C): Rewrite it here.
(with_possible_nonzero_bits, with_possible_nonzero_bits2,
with_certain_nonzero_bits2): New predicates.
* tree-ssanames.c (get_nonzero_bits): Handle INTEGER_CST.
