[RISCV] Custom type legalize i8/i16 UDIV/UREM/SDIV on RV64 so we can use divuw/remuw/divw.
This makes our i8/i16 codegen more similar to the i32 codegen.
I've also added computeKnownBits support for DIVUW/REMUW so
that we can remove zero extending ANDs from the output. Without
this we end up turning DIVUW/REMUW back into DIVU/REMU via some
isel patterns.
