   The differences between High GIMPLE and Low GIMPLE are the
   following:

   1- Lexical scopes are removed (i.e., GIMPLE_BIND disappears).

   2- GIMPLE_TRY and GIMPLE_CATCH are converted to abnormal control
      flow and exception regions are built as an on-the-side region
      hierarchy (See tree-eh.c:lower_eh_constructs).

   3- Multiple identical return statements are grouped into a single
      return and gotos to the unique return site.

   Match a return statement with a label.  During lowering, we identify
   identical return statements and replace duplicates with a jump to
   the corresponding label.
