  |     [PR rtl-optimization/116420] Fix interesting block bitmap DF dataflow
  |     
  |     The DF framework provides us a way to run dataflow problems on sub-graphs.
  |     Naturally a bitmap of interesting blocks is passed into those routines.   At a
  |     confluence point, the DF framework will not mark a block for re-processing if
  |     it's not in that set of interesting blocks.
