[Bug middle-end/30141] New: nested function can produce invalid gimple

[pinskia at gcc dot gnu dot org]

Testcase:
extern int dummy (int *);
void foo(int i)
{
  void bar() { int y=i; }
  dummy(&i);
}
---------------
We get, i is ADDRESSABLE here:
  struct FRAME.foo FRAME.0;

  FRAME.0.i = i;  
  dummy (&FRAME.0.i);
  return;

Hmm, I think my patch is correct but too "stupid"; we should be able just to
mark the argument as non-addressable and a gimple register since we replaced
all uses of it with an access via a frame struct.
