Hmm, actually in the modified testcase we miss the indirect inlining and we
also never turn the indirect call into direct call.
The problem is that pointer cast is in the way
  one.0_1 = (unsigned char (*Calculable) (void)) one;
  D.3314_7 = one.0_1 ();

Martin, Richi, this is really yours area.
I think both indirect inlining and constant propagation should be able to get
past the cast especially when there is no type mismatch in the testcase.
