[LegalizeTypes] Teach SoftenFloatOp_SELECT_CC to handle operand 2 or 3 being softened.

This can only happen on X86 when fp128 is a legal type, but we
go through softening to generate libcalls. This causes fp128 to
be softened to fp128 instead of an integer type. This can be
removed if D67128 lands.
