[SelectionDAGBuilder][X86] Don't form FMAXNUM for f16 vectors if FMAXNUM needs to be promoted. (#114943)
In #70357, I changed a isLegalOrCustom to isLegalOrCustomOrPromote in
visitSelect to enable integer min/max to be formed when the operation
was promoted. Unfortunately, this also affected floating point. For
floating point, fmaxnum may require a libcall so we also need to check
if the operation on the promoted type is legal or custom.
Other changes to RISC-V have seen made the original change untested so
this patch restores the original isLegalOrCustom.
Fixes #114520.
