	* params.def (PARAM_LOGICAL_OP_NON_SHORT_CIRCUIT): New param.
	* tree-ssa-ifcombine.c (ifcombine_ifandif): If
	--param logical-op-non-short-circuit is present, override
	LOGICAL_OP_NON_SHORT_CIRCUIT value from the param.

	* lib/target-supports.exp (logical_op_short_circuit): Remove.
	* gcc.dg/builtin-bswap-7.c: Remove logical_op_short_circuit
	effective target, drop -mbranch-cost= options from the test and
	instead pass --param logical-op-non-short-circuit=0 or
	--param logical-op-non-short-circuit=1 depending on what the
	tests meant to test.
