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 41c35d6d2f Unify lookup from within not-yet-defined defaulted special members: use common
code for handling triviality, deletedness and constexpr. Fix a few bugs in
these, particularly related to mutable members, and remove some dead code.

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 af136f8191 PR13381, part 2: when determining if a defaulted special member function should
be defined as deleted, take cv-qualifiers on class members into account when
looking up the copy or move constructor or assignment operator which will be
used for them.

Richard Smith c5f98f343b [class.copy]p23: Fix an assertion caused by incorrect argument numbering in a
diagnostic, add a test for this paragraph, and tighten up the diagnostic wording
a little.

Douglas Gregor 74f7d50f6a When overload resolution picks an implicitly-deleted special member
function, provide a specialized diagnostic that indicates the kind of
special member function (default constructor, copy assignment
operator, etc.) and that it was implicitly deleted. Add a hook where
we can provide more detailed information later.
