  [RISCV] Have customLegalizeToWOp truncate to the original type instead of i32 now that we use it for i8/i16 as well.

239cfbccb0509da1a08d9e746706013b732e646b add support for legalizing
i8/i16 UDIV/UREM/SDIV to use *W instructions. So we need to truncate
to i8/i16 if we're legalizing one of those.
