Template instantiation for qualified declaration reference

expressions. We are now missing template instantiation logic for only
three classes of expressions:
- Blocks-related expressions (BlockExpr, BlockDeclRefExpr)
- C++ default argument expressions
- Objective-C expressions
Additionally, our handling of DeclRefExpr is still quite poor, since
it cannot handle references to many kinds of declarations.
As part of this change, converted the TemplateExprInstantiator to use
iteration through all of the expressions via clang/AST/StmtNodes.def,
ensuring that we don't forget to add template instantiation logic for
any new expression node kinds.

Representation of and template instantiation for member

The disambiguation process for ambiguous paren expressions is not "side effects free", e.g:
...
(T(*)(int[x+y]));
is an (invalid) paren expression, but "x+y" will be parsed as part of the (rejected) type-id,
so unnecessary Action calls are made for an unused (and possibly leaked) "x+y".
Use a different scheme, similar to parsing inline methods. The parenthesized tokens are cached,
the context that follows is determined (possibly by parsing a cast-expression),
and then we re-introduce the cached tokens into the token stream and parse them appropriately.

Introduce a new expression type, CXXUnresolvedConstructExpr, to
...
describe the construction of a value of a given type using function
syntax, e.g.,
T(a1, a2, ..., aN)
when the type or any of its arguments are type-dependent. In this
case, we don't know what kind of type-construction this will be: it
might construct a temporary of type 'T' (which might be a class or
non-class type) or might perform a conversion to type 'T'. Also,
implement printing of and template instantiation for this new
expression type. Due to the change in Sema::ActOnCXXTypeConstructExpr,
our existing tests cover template instantiation of this new expression
node.

This patch provides preliminary support for non-fragile instance variables on the GNU runtime.

It currently requires a patches to GNU libobjc (and so is not enabled by default) which are currently
being tested and reviewed by GNUstep before being pushed upstream.
This patch does not allow support for synthesized ivars, but does provide the infrastructure
needed for supporting them.

Fix for PR2386: distinguish between insertion and replacements in the
...
delta tree.
The issue is roughly a conflict in ReplaceText between two kinds of
uses. One, it should be possible to replace a replacement: for example, the
ObjC rewriter calls ReplaceStmt for an expression, then replaces the resulting
expression with another expression. Two, it should be possible to
replace text that already has text inserted before it: for example, the
HTML rewriter inserts a bunch of tags at the beginning of the line, then
tries to escape the first character on the line. This patch
distinguishes the two cases by storing the deltas separately;
essentially, replacements and insertions no longer interfere with
each other.
Another possibility would be to add some sort of flag to ReplaceText, but
this seems a bit more intuitive and flexible.
There are a few downsides to the current solution: one is that there isn't
any way to remove/replace an insertion without touching additional
surrounding text; if such an operation turns out to be useful, an
additional method or flag can be added. Another is that an insertion
and replacing a string of length zero are distinct operations; I'm not
sure how to resolve this, or whether it will be confusing in practice.
This is relatively sensitive code, so please test and tell me if
anything breaks.

Implement explicit instantiations of member classes of class templates, e.g.,
...
template<typename T>
struct X {
struct Inner;
};
template struct X<int>::Inner;
This change is larger than it looks because it also fixes some
a problem with nested-name-specifiers and tags. We weren't requiring
the DeclContext associated with the scope specifier of a tag to be
complete. Therefore, when looking for something like "struct
X<int>::Inner", we weren't instantiating X<int>.
This, naturally, uncovered a problem with member pointers, where we
were requiring the left-hand side of a member pointer access
expression (e.g., x->*) to be a complete type. However, this is wrong:
the semantics of this expression does not require a complete type (EDG
agrees).

C++98, we just emit an extension warning.
- In C++0x, an explicit instantiation must be in a namespace
enclosing the original template. C++98 has no such requirement.
Also, fixed a longstanding FIXME regarding the integral type that is

still aren't instantiating the definitions of class template members,

for explicit instantiations (but are not yet implemented).

Implement the semantics of the injected-class-name within a class

template. The injected-class-name is either a type or a template,

parameters in declaration order.
As part of this, add logic for canonicalizing declarations, and be
sure to canonicalize declarations used in template names and template
arguments.
A TagType is dependent if the declaration it references is dependent.
