[RegisterCoalescer] Add wrapper for Erasing Instructions
Summary:
To delete an instruction the coalescer needs to call
eraseFromParent()
on the MachineInstr, insert it in the ErasedInstrs list and update
the
Live Ranges structure. This patch re-factors the code to do all that
in
one function. This will also fix cases where previous code wasn't
inserting deleted instructions in the ErasedList.
