* 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.
