	* tree.def (PAREN_EXPR): New tree code.
	* fold-const.c (fold_unary): Remove PAREN_EXPR around constants
	and PAREN_EXPR.
	* tree-pretty-print.c (dump_generic_node): Handle PAREN_EXPR.
	* expr.c (expand_expr_real_1): Likewise.
	* tree-inline.c (estimate_num_insns_1): Likewise.
	* tree-complex.c (expand_complex_move): Likewise.
	* tree-vectorizer.c (vect_is_simple_use): Treat PAREN_EXPR (x)
	as plain x.

CCP should also see through PAREN_EXPRs. VRP shouldn't; I'm not sure about copyprop.
