/* Here's the deal: f4 is inlined into main, f3 is inlined into f4, f2 is
   inlined into f1. The DIE of main should contain DW_TAG_inlined_subroutines
   children for f4, f3, f2 and f1. Also, there should be a DIE representing
   and out of line instance of f4, aside the DIE representing its abstract
   instance.
   We used to fail to emit debugging info for t1, because it was moved
   inside the (inlined) block of f1, marked as abstract, then we'd crash.  */
