  Log Message:
  [PhaseOrdering] Add test for incorrect merge function scheduling

Add an -enable-merge-functions option to allow testing of function
merging as it will actually happen in the optimization pipeline.
Based on that add a test where we currently produce two identical
functions without merging them due to incorrect pass scheduling
under the new pass manager.
