  Log Message:
  -----------
  [LoongArch] Add codegen support for the bitwise binary operations and part of other operations

Reference:
https://llvm.org/docs/LangRef.html#bitwise-binary-operations
https://llvm.org/docs/LangRef.html#other-operations

The reason why other operations are implemented here is that some
bitwise binary operations depend on them. For example, on loongarch32,
`shl` over i64 data requires `select`.
