	PR rtl-optimization/19348
	* recog.c (peephole2_optimize): Do global life update if some peephole
	decides it doesn't need at least one of its inputs and that change
	influences liveness at the start of the basic block.
	
	* basic-block.h (EXECUTE_IF_AND_COMPL_IN_REG_SET): Needs 2 REGSET
	arguments instead of 1.
