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.

into one. These were all performing almost identical checks, with different bugs
in each of them.
This fixes PR12806 (we weren't setting the exception specification for an
explicitly-defaulted, non-user-provided default constructor) and enforces
8.4.2/2's rule that an in-class defaulted member must exactly match the implicit
parameter type.

For compatibility with gcc, clang will now parse gcc attributes on
function definitions, but issue a warning if the attribute is not a
thread safety attribute. Warning controlled by -Wgcc-compat.

understand).
