[LegalizeTypes][RISCV][X86] Legalize FP_ROUND to libcall in SoftPromoteHalfRes_FP_ROUND if the input type is softened. (#119481)
Previously we created an FP_TO_FP16 and legalized it in
SoftenFloatOp_FP_ROUND. This caused i16 to be sent to call lowering
instead of f16. This results in the ABI not being followed if f16 is
supposed to be passed in a different register than i16.
Looking at the libgcc binary for the library function it appears the value
is returned in xmm0 so the X86 test was being miscompiled before.
Fixes #107607.
