sse.md (<code><mode>3 smaxmin:VI124_128 expander): Use nonimmediate_operand instead of register_operand predicate for operands 1... 

* config/i386/sse.md (<code><mode>3 smaxmin:VI124_128 expander): Use
	nonimmediate_operand instead of register_operand predicate for operands
	1 and 2, force them into registers if expanding them as comparison.
	(<code><mode>3 umaxmin:VI124_128 expander): Similarly.  For UMAX
	V8HImode force into register just operand 1.
