Better diagnostic for superfluous scope specifier inside a class definition for member functions. + Fixit.

Example: 
class A {
   void A::foo(); //warning: extra qualification on member 'foo'

function template specialization against the desired function type

in CXXRecordDecl itself. Yes, this is also part of <rdar://problem/8459981>.

This reinstates r114924, with one crucial bug fix: we were ignoring
the implicit fields created by anonymous structs/unions when updating
the bits in CXXRecordDecl, which means that a class/struct containing
only an anonymous class/struct would be considered "empty". Hilarity
follows.

unless we're on a platform without __cxa_atexit (or use thereof has been
disabled).  This patch actually just disables the check completely for
static locals, but I've filed http://llvm.org/bugs/show_bug.cgi?id=8176 to
track the platform-specific fix.

of a binary expression, continue on and parse the right-hand side of
the binary expression anyway, but don't call the semantic actions to
type-check. Previously, we would see the error and then, effectively,
skip tokens until the end of the statement. 

The result should be more useful recovery, both in the normal case
(we'll actually see errors beyond the first one in a statement), but
it also helps code completion do a much better job, because we do
"real" code completion on the right-hand side of an invalid binary
expression rather than completing with the recovery completion. For
example, given

  x = p->y

if there is no variable named "x", we can still complete after the p->
as a member expression. Along the recovery path, we would have
completed after the "->" as if we were in an expression context, which
is mostly useless.

slot.  The easiest way to do that was to bundle up the information
we care about for aggregate slots into a new structure which demands
that its creators at least consider the question.

I could probably be convinced that the ObjC 'needs GC' bit should
be rolled into this structure.
Implement generalized copy elision.  The main obstacle here is that
IR-generation must be much more careful about making sure that exactly

Remove CXXRecordDecl::getDefaultConstructor(), an inherently unsafe function due to lazy declaration of default constructors. Now that __has_nothrow_constructor doesn't use it anymore, part of PR8101 is fixed.

Have __has_nothrow_copy use Sema's lookup routines. This fixes the problem with not finding implicitly declared copy constructors, part of PR8107.

Fixes PR8110, and thus PR8109, PR8097, and parts of PR8101, PR8105 and PR8107. Only a few traits have tests for incomplete arrays, since I'm not yet clear what the result for them should be; Howards wants to file a DR to change the standard.
