  [MemProf] Ensure all callsite clones are assigned a function clone (#150735)

Fix a bug in function assignment where we were not assigning all
callsite clones to a function clone. This led to incorrect call updates
because multiple callsite clones could look like they were assigned to
the same function clone.

Add in a stat and debug message to help identify and debug cases where
this is still happening.
