Remove pre-standard restriction on explicitly-defaulted copy constructors with
'incorrect' parameter types, and instead just make those special members
non-trivial as the standard requires.
This required making CXXRecordDecl correctly handle classes which have both a
trivial and a non-trivial special member of the same kind.
This also fixes PR13217 by reimplementing DiagnoseNontrivial in terms of the
new triviality computation technology.

We don't support any C++11 attributes that appertain to declaration specifiers so reject
the attributes in parser until we support them; this also conforms to what g++ 4.8 is doing.

When performing the simplistic overload resolution for single-argument methods,
don't check the best overload for ambiguity with itself when the best overload
doesn't happen to be the first one.
Fixes PR13480.

being used in an exception specification in a way which isn't otherwise
ill-formed in C++98: this warning also incorrectly triggered on uses of 'this'
inside thread-safety attributes, and the mechanism required to tell these cases
apart is more complex than can be justified by the (minimal) value of this part
of -Wc++98-compat.

basic source character set in C++98. Add -Wc++98-compat diagnostics for same in
literals in C++11. Extend such support to cover string literals as well as
character literals, and mark N2170 as done.
This seems too minor to warrant a release note to me. Let me know if you disagree.

those issues will be fixed by subsequent patches.

This also adds a -Wc++98-compat-pedantic for warning on constructs which would
be diagnosed by -std=c++98 -pedantic (that is, it warns even on C++11 features
which we enable by default, with no warning, in C++98 mode).

the -Wc++98-compat-variadic-templates sub-flag and -Wc++98-compat to include
it.
