Add mir-check-debug pass to check MIR-level debug info. For IR-level, currently, LLVM have debugify + check-debugify to generate and check debug IR. Much like the IR-level pass debugify, mir-debugify inserts sequentially increasing line locations to each MachineInstr in a Module, But there is no equivalent MIR-level check-debugify pass, So now we support it at "mir-check-debug".
