We have implementation divergence with libc++'s ~unique_ptr()
behavior, so make sure QScopedPointer behaves the same way as
unique_ptr is spec'ed, even though to check it, one has to rely
on UB, at least according to LLVM devs (I don't think the test
as written invokes UB).
Code's a bit duplicated. I tried making the struct a template,
but it's just too much of a fuss (needs a variable template,
which we can't use in Qt 5), so I decided to use cut'n'paste.
Task-number: QTBUG-137069
