[LoongArch] Add codegen support for division operations
These operations include sdiv/udiv/srem/urem.
As the ISA [https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html#_div_wudu_mod_wudu]
described, when the divisor is 0, the result can be any value, but no
exception will be triggered. Unlike gcc, which by default emit code
that checks divide-by-zero after the division or modulus instruction,
we only emit this check when the `-loongarch-check-zero-division`
option is passed.
