[DAGCombiner][X86] Pass the CmpOpVT to reduceSelectOfFPConstantLoads so X86 can exclude fp128 compares.

The X86 decision assumes the compare will produce a result in an XMM
register, but that can't happen for an fp128 compare since those
go to a libcall the returns an i32. Pass the VT so X86 can check
the type.
