	* config/microblaze/predicates.md: Add cmp_op predicate.
	* config/microblaze/microblaze.md: Add branch_compare instruction 
	which uses cmp_op predicate and emits cmp insn before branch.
	* config/microblaze/microblaze.c (microblaze_emit_compare): Rename 
	to microblaze_expand_conditional_branch and consolidate logic.
	(microblaze_expand_conditional_branch): emit branch_compare
	insn instead of handling cmp op separate from branch insn.
