Currently, some function level properties are passed by `TargetMachine`, by calling [`TargetMachine::resetTargetOptions()`](https://llvm.org/doxygen/classllvm_1_1TargetMachine.html#af0a50afebb9bed07d36be2bac4c6f729) before instruction selection. Now we are trying to port codegen pipeline to new pass manager, and this is not friendly to pass parallelization, we may move this part to a new analysis pass or something else and make it accessible to other codegen infrastructures (e.g. `TargetLowering`).
