[llvm-branch-commits] [llvm] [LoongArch] Fold selects sharing operands with binary operations (PR #215520)

`select-binop-combine.ll` already performs a similar transformation at the IR level. After running `opt -O2`, the resulting code has the same effect as this combine. Do we still need to handle this separately in the backend?
