[RegisterCoalescer] Account for instructions deleted by removePartialredunduncy and in WorkList
Summary:
removePartialRedundency optimization introduces a state in the
RegisterCoalescer where an instruction pointed to in the WorkList
is deleted from the MBB and then removed from the ErasedList.
This patch updates the ErasedList to be used globally by not erasing
erased Instructions from it to solve the problem.
The patch also accounts for the case where an Instruction was previously
deleted and the same memory was reused by BuildMI to create a new instruction.
