Off by one use of abort() instead of gcc_assert()

[Christophe Jaillet]

Not really a patch, because I'm currently not able to bootstrap gcc :-(, but
anyway :

In file "ipa-type-escape.c", in function "analyze_variable", there is one of
the last construction of type : if () abort() as stated in the wiki page
"partial transitions"

=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+
  if (TREE_CODE (global) == VAR_DECL)
    {
      if (DECL_INITIAL (global))
 walk_tree (&DECL_INITIAL (global), scan_for_refs,
     NULL, visited_nodes);
    }
  else abort();
=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+


that could certainly be turned into :

=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+
   gcc_assert(TREE_CODE (global) != VAR_DECL);

   if (DECL_INITIAL (global))
      walk_tree (&DECL_INITIAL (global), scan_for_refs,
                       NULL, visited_nodes);
=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+
