Fix machine-outliner-regsave.mir. Touch %lr to fix the following -verify-machineinstrs issue

  *** Bad machine code: Using an undefined physical register ***                                                                                        
  - function:    bar                                       
  - basic block: %bb.0  (0x1325e00)                                                                                  
  - instruction: early-clobber $sp = STRXpre $lr, $sp(tied-def 0), -16
