* config/m68hc11/m68hc11.md ("bitcmpqi" split): No need to test the
	mode of operand 0.
	(peephole2 optimize const load): Likewise for operand 2.
	("*rotlhi3_with_carry"): Change pattern to a const 1 rotate which
	clobbers CC_REGNUM.
	("*rotrhi3_with_carry"): Likewise.
	(ashift:DI 1 split): Update pattern to create the above rotate.
	(lshiftrt:DI 1 split): Likewise.
