Richard Smith dd5619feac PR28978: If we need overload resolution for the move constructor of an
anonymous union member of a class, we need overload resolution for the move
constructor of the class itself too; we can't rely on Sema to do the right
thing for us for anonymous union types.

Richard Smith 566184ac75 When a special member is explicitly defaulted outside its class, and we reject
the defaulting because it would delete the member, produce additional notes
explaining why the member is implicitly deleted.

Richard Smith c91d12ce80 Take cv-qualifiers on fields of class type into account when determining
whether a defaulted special member function should be deleted.

Richard Smith e3b28bc363 Move detection of reference members binding to temporaries from building of
CXXCtorInitializers to the point where we perform the questionable lifetime
extension. This exposed a selection of false negatives in the warning.

Richard Smith cf8ec8dad6 Implement DR1402: if a field or base class is not movable, the derived class's
move constructor/move assignment operator are not declared, rather than being
defined as deleted, so move operations on the derived class fall back to
copying rather than moving.

If a move operation on the derived class is explicitly defaulted, the
unmovable subobject will be copied instead of being moved.
