Previously if an enumeration was used in a nested name specifier in pre-C++11
language dialect, error message was 'XXX is not a class, namespace, or scoped
enumeration'. This patch removes the word 'scoped' as in C++11 any enumeration
may be used in this context.

"expected" is at the start of the word and will no longer accept typos such as "junkexpected-*" as a valid "expected-*" directive. A very few test-cases had to be amended to adhere to the new rule.

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.

* s/nonstatic/non-static/ in the diagnostics, since the latter form outvoted
the former by 28-2 in our diagnostics.
* Fix the "use of member in static member function" diagnostic to correctly
detect this situation inside a block or lambda.
* Produce a more specific "invalid use of non-static member" diagnostic for
the case where a nested class member refers to a member of a
lexically-surrounding class.

that 'this' can be used in the brace-or-equal-initializer of a
non-static data member, and C++11 [expr.prim.lambda]p9, which says
that lambda expressions not in block scope can have no captures, side
fully with C++11 [expr.prim.general]p4 by allowing 'this' to be
captured within these initializers. This seems to be the intent of
non-static data member initializers.

Split out a new ExpressionEvaluationContext flag for this case, and don't treat
it as unevaluated in C++11. This fixes some crash-on-invalids where we would
allow references to class members in potentially-evaluated constant expressions
in static member functions, and also fixes half of PR10177.
The fix to PR10177 exposed a case where template instantiation failed to provide
a source location for a diagnostic, so TreeTransform has been tweaked to supply
source locations when transforming a type. The source location is still not very
good, but MarkDeclarationsReferencedInType would need to operate on a TypeLoc to
improve it further.
Also fix MarkDeclarationReferenced in C++98 mode to trigger instantiation for
static data members of class templates which are used in constant expressions.
This fixes a link-time problem, but we still incorrectly treat the member as
non-constant. The rest of the fix for that issue is blocked on PCH support for
early-instantiated static data members, which will be added in a subsequent
patch.
