Works on trunk (but not during early inlining).  From early inlining we now get

<bb 2>:
  f.x = g;
  D.2126_6 = f.x;
  D.2127_7 = D.2126_6 (3);

and early FRE turns that into a direct call:

  f$x_8 = g;
  D.2126_6 = f$x_8;
  D.2125_7 = g (3);

which is then inlined by IPA inlining:

int main(int, char**) (int argc, char * * argv)
{
<bb 2>:
  return 0;

}

Fixed.
