i386.md (movsfcc, [...]): Use emit_store_flag to support LT, LE, GE, and GT signed integer comparisons.

�
	* i386.md (movsfcc, movdfcc, movxfcc): Use emit_store_flag
	to support LT, LE, GE, and GT signed integer comparisons.
	(movsfcc+1, movsfcc+2, movdfcc+1, movdfcc+2,
	movxfcc+1, movxfcc+2): Pattern doesn't match if the comparison
	is LT, LE, GE, or GT.
	(movdicc): Remove code resulting from an earlier patch which
	didn't apply correctly.
