	<BIT_XOR_EXPR>: Optimize ~X\|X and X\|~X as -1. <BIT_AND_EXPR>: Optimize ~X&X and X&~X as 0. <TRUTH_AND_EXPR, TRUTH_ANDIF_EXPR>: Optimize !X&&X and X&&!X as false. <TRUTH_OR_EXPR, TRUTH_ORIF_EXPR>: Optimize !X\|\|X and !X\|\|X as true. <TRUTH_XOR_EXPR>: Optimize !X^X and X^X! as true. Now that TRUTH_XOR_EXPR is a commutative tree code, don't test whether arg0 is a constant. * gcc.dg/20040527-1.c: New test case. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@83733 138bc75d-0d04-0410-961f-82ee72b054a4
