Construct the pass tree.  The sequencing of passes is driven by
   the cgraph routines:

   finalize_compilation_unit ()
       for each node N in the cgraph
           cgraph_analyze_function (N)
               cgraph_lower_function (N) -> all_lowering_passes

   If we are optimizing, compile is then invoked:

   compile ()
       ipa_passes ()                    -> all_small_ipa_passes
                                        -> Analysis of all_regular_ipa_passes
        * possible LTO streaming at copmilation time *
                                        -> Execution of all_regular_ipa_passes
        * possible LTO streaming at link time *
                                        -> all_late_ipa_passes
       expand_all_functions ()
           for each node N in the cgraph
               expand_function (N)      -> Transformation of all_regular_ipa_passes
                                        -> all_passes

void pass_manager::register_dump_files ( struct opt_pass *  pass, int  properties  )

private

Register the dump files for the pass_manager starting at PASS.
   PROPERTIES reflects the properties that are guaranteed to be available at
   the beginning of the pipeline.
