Kaz approved the SH parts and reported that there were no new failures
on sh4-unknown-linux-gnu (thanks).

Sorry, this must have slipped through the cracks.  Thanks for pinging it.

	* builtins.c (expand_cmpstr, expand_cmpstrn): New functions.
	(expand_builtin_strcmp, expand_builtin_strncmp): Use them.  Remove
	references to HAVE_cmpstr{,n}si and CODE_FOR_cmpstr{,n}si.
	* config/m32c/blkmov.md (cmpstrsi): Fix predicates of operands 1 and 2.
	Add predicates for operands 0 and 3.
	* config/rx/rx.md (cmpstrnsi): Remove force_operand for the length
	operand.
	* config/sh/sh.md (cmpstrnsi): Change the length predicate from
	immediate_operand to nonmemory_operand.

OK.
jeff
