  Log Message:
  -----------
  Pre-commit reproducer for argument copy elison related bug

Adding test case related to
  https://github.com/llvm/llvm-project/issues/89060

It shows that after argument copy elison the scheduler may reorder
a load of the input argument and a store to the same fixed stack
entry (the fixed stack entry that is reused for the local variable).
