Craig Topper 9a1eded9b9 [RISCV] Custom legalize f16/bf16 FCOPYSIGN with Zfhmin/Zbfmin. (#107039) ...

The LegalizeDAG expansion will go through memory since i16 isn't a legal
type. Avoid this by using FMV nodes.

Similar to what we did for #106886 for FNEG and FABS. Special care is
needed to handle the Sign operand being a different type.
