Fix to mn10300 cmpsi pattern

[Matt Hiller]

	The cmp instruction on mn10300 does not allow both operands to be
the same register. The cmpsi pattern, as it presently is, looks for
situations where a register is compared to itself, but doesn't compensate
properly when it finds one. The following patch fixes this.

	* config/mn10300/mn10300.md (cmpsi): Fix first alternative's
	output template.
