[Bug tree-optimization/21093] New: missed tail call optimization when local address could escape

[pinskia at gcc dot gnu dot org]

Missed tail call optimization when local address could escape but not on the condition:
void f(void);
void f1(int *);

void g(int i, int j)
{
  if (j)
    return f();
  return f1(&i);
}

This might be a reduced testcase from fold_binary to fold_build2 where we have this issue, but I have 
not looked through all of the conditionals to see if this is true.
