If we have:
   @class Foo, Bar;
source ranges for both start at '@', so 'Bar' will end up overriding
'Foo' even though the cursor location was at 'Foo'.

exception specifications on member functions until after the closing
'}' for the containing class. This allows, for example, a member
function to throw an instance of its own class. Fixes PR12564 and a
fairly embarassing oversight in our C++98/03 support.

in the declaration of a non-static member function after the
(optional) cv-qualifier-seq, which in practice means in the exception
specification and late-specified return type. 

The new scheme here used to manage 'this' outside of a member function
scope is more general than the Scope-based mechanism previously used
for non-static data member initializers and late-parsesd attributes,
because it can also handle the cv-qualifiers on the member
function. Note, however, that a separate pass is required for static
member functions to determine whether 'this' was used, because we
might not know that we have a static function until after declaration
matching.

Finally, this introduces name mangling for 'this' and for the implicit
'this', which is intended to match GCC's mangling. Independent
verification for the new mangling test case would be appreciated.

Fixes PR10036 and PR12450.

The result of the Microsoft __uuidof operator must be considered a global lvalue during constant expression evaluation.
Otherwise we would get this error in C++11 mode (because of a recent change):
   error: non-type template argument of type 'const _GUID *' is not a constant expression

For code like:
template <const GUID* g = &__uuidof(struct_with_uuid)>
class COM_CLASS { };

includes a patch from Matthias Kleine with a regression testcase!

Adds a new iterator 'data_iterator' to OnDiskHashTable which doesn't try to
reconstruct the external_key from the internal_key, which is useful for traits
that don't store enough information to do that mapping in their key. Also
deletes the 'item_iterator' from OnDiskHashTable as dead code.

Change _mm256_permute4x64_epi64 and _mm256_permute4x64_pd to use builtin_shufflevector instead of specific builtins. Old builtins will be removed from llvm now that vpermq/vpermpd are supported by shuffle lowering code.

Passing -verify to clang without -cc1 or -Xclang silently passes (with a
printed warning, but lit doesn't care about that). This change adds -cc1 or,
as is necessary in one case, -Xclang to fix this so that these tests are
actually verifying as intended.

I'd like to change the driver so this kind of mistake could not be made, but
I'm not entirely sure how. Further, since the driver only warns about unknown
flags in general, we could have similar bugs with a misspellings of arguments
that would be nice to find.

initialize an array of unsigned char. Outside C++11 mode, this bug was benign,
and just resulted in us emitting a constant which was double the required
length, padded with 0s. In C++11, it resulted in us generating an array whose
first element was something like  i8 ptrtoint ([n x i8]* @str to i8).
