  -----------
  [flang] Record the evaluations that branch to each evaluation (#225755)

The PFT records where each branch goes, but not where it comes from, so
asking whether anything branches into a construct means walking the
whole procedure.

Record the reverse edges beside the forward ones, and print them in PFT
dumps so both directions of the branch graph are visible.
