Rewrite part of and_comparisons_1 into match.pd.

2019-09-16  Martin Liska  <mliska@suse.cz>

	* genmatch.c (dt_node::append_simplify): Do not print
	warning when we have duplicate patterns belonging
	to a same simplify rule.
	* gimple-fold.c (and_comparisons_1): Remove matching moved to match.pd.
	(maybe_fold_comparisons_from_match_pd): Handle
	tcc_comparison as a results.
	* match.pd: Handle (X == CST1) && (X OP2 CST2) conditions.
