[Bug middle-end/35560] Missing CSE/PRE for memory operations involved in virtual call.

Well, the middle-end thinks that *ap is clobbered by the calls to foo/bar
(which it obviously is).  The middle-end has no idea that the _vptr member
of *ap is special and not clobbered (is it?).  We do not have a suitable way
to represent this either.
