LOG: Revert "[MemProf] Context disambiguation cloning pass [patch 3/4]"
This reverts commit bf6ff4fd4b735afffc65f92a4a79f6610e7174c3.
There is a bot failure where we are getting the correct remarks output
but in a different order. I'll need to investigate to see where we are
having nondeterministic behavior.
