What happens is that in expand_call_inline we fail the inlining via
an error, but at this point of course the edge points to the inline
clone and that stays so.

I suppose when expand_call_inline fails we have to re-direct the
edge to the original function (huh, eventually make sure it is not
optimized away as well).

Or, finally, _never_ fail that late
