  Log Message:
  [SCEV] Remove incorrect assert

Fix assertion failure reported on D113349 by removing the assert.
While the produced expression should be equivalent, it may not
be strictly the same, e.g. due to lazy nowrap flag updates. Similar
to what the main createSCEV() code does, simply retain the old
value map entry if one already exists.
