I think the additions here look good, but we're missing a test for a call to
`::delete` for a class that declares a destroying operator delete. Such a test
is interesting for both the Itanium and MSVC ABIs for different reasons (the
complete object destructor is called followed by global operator delete for
Itanium; the deleting destructor is called and it calls the complete destructor
and then the global operator delete for MSVC).
