sse.md (copysign<mode>3): Use "and-not" SSE instruction instead of "and" with inverted sign bit mask value.
* config/i386/sse.md (copysign<mode>3): Use "and-not" SSE instruction
instead of "and" with inverted sign bit mask value. Use
"nonimmediate_operand" for operand 1 and operand 2 predicate.
Allocate registers only for operand 4 and operand 5.
