Maybe add a note "qualified call to 'A::f' is treated as a virtual call to 'f'
due to -fapple-kext"?
(Also, how about adding "has undefined behavior" before the semicolon in the
warning?)
I also wonder if we should add an `performsVirtualDispatch(const LangOptions
&)` to `MemberExpr`, instead of the somewhat more opaque check for a qualifier
here. (There are other places where we perform a similar check, such as
`MarkExprReferenced` and `Sema::MarkMemberReferenced`, which get the kext case
wrong.)

----------------
Use `hasQualifier` instead of `getQualifier`.
