If the destination isn't any of the incoming sources then we can avoid one of the moves at the end. This half works around the problem proposed in #3794, but doesn't solve the entire problem. To solve the other half of the moving problem means we need to solve the SRA allocation problem for this temporary register with addsub/subadd, so it gets allocated for both the FMA operation and the XOR operation.
