[Bug middle-end/23872] New: .t02.original dump weirdness

["dann at godzilla dot ics dot uci dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

Using gcc -O2 -fdump-tree-all -S 
to compile: 

int bar (void) {   return 0;}

int foo (int reject) {   int result = 0;   return result;}

the .t02.original dump looks like:
;; Function bar (bar)
;; enabled by -tree-original
{
  return 0;
}
;; Function foo (foo)
;; enabled by -tree-original
{
  int result = 0;

    int result = 0; <--- this line appears twice...
  return result;
}

If the order of the 2 functions is reversed in the file then the dump looks like:

;; Function foo (foo)
;; enabled by -tree-original
{
  int result = 0;
  <STATEMENT_LIST>  <--- the return does not appear...
}
;; Function bar (bar)
;; enabled by -tree-original
{
  return 0;
}

Using just -fdump-tree-original then the dump for "foo" always looks like the
second version.
