1) Allow the Index library (and any other interested client) to walk
the set of declarations for a given tag (enum, union, class,
whatever). At the moment, this information is not readily available.
2) Reduce our dependence on TagDecl::TypeForDecl being mapped down
to a TagType (for which getDecl() will return the tag definition, if
one exists). This property won't exist for class template partial
specializations.
3) Make the canonical declaration of a TagDecl actually canonical,
e.g., so that it does not change when the tag is defined.

Note: One day, it might be useful to consider adding this info to DeclGroup (as the comments in FunctionDecl/VarDecl suggest). For now, I think this works fine. I considered moving this to ValueDecl (a common ancestor of FunctionDecl/VarDecl/FieldDecl), however this would add overhead to EnumConstantDecl (which would burn memory and isn't necessary).

The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.
This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

C++. This logic is required to trigger implicit instantiation of
function templates and member functions of class templates, which will
be implemented separately.
This commit includes support for -Wunused-parameter, printing warnings
for named parameters that are not used within a function/Objective-C
method/block. Fixes <rdar://problem/6505209>.

within a template now have a link back to the enumeration from which
they were instantiated. This means that we can now find the
instantiation of an anonymous enumeration.

template to the FunctionDecls from which they were instantiated. This
is a necessary first step to support instantiation of the definitions
of such functions, but by itself does essentially nothing.

parm var decls in leopard cocoa.h end up using this abbreviation,
which shrinks the bitcode file by about 50K: 7217736->7167120.
