    [RegisterCoalescer] Add wrapper for Erasing Instructions

          To delete an instruction the coalescer needs to call
          on the MachineInstr, insert it in the ErasedInstrs list and update
          Live Ranges structure. This patch re-factors the code to do all that
          one function. This will also fix cases where previous code wasn't
          inserting deleted instructions in the ErasedList.
