Move away from 'general' / 'generalized' as a way of identifying C++11
...
attribute syntax. There's nothing generalized about this; it's one of
several first-class attribute syntaxes we support, all of which are
more-or-less equally general.
As discussed on cfe-commits, we may want to revisit this if we start allowing
this syntax as an extension in C (or if C adopts the syntax), but hopefully
this diagnostic wording will be crystal clear to everyone in the mean time.

Properly compute triviality for explicitly-defaulted or deleted special members.
...
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.
