-Introduce Decl::getASTContext() which returns the reference from the TranslationUnitDecl that it is contained in.

The general idea is that Decls can point to their own ASTContext so that it is no longer required to "manually" keep track and make sure that you pass the correct ASTContext to Decls' methods, e.g. methods like Decl::getAttrs should eventually not require a ASTContext parameter.

of template instantiation, we were dropping cv-qualifiers on the
instantiated type in a few places. This change reshuffles the
type-instantiation code a little bit so that there's a single place
where we add qualifiers to the instantiated type, so that we won't end
up with this same bug in the future.

non-dependent parameter types. Instead, class template partial
specializations perform a final check of all of the instantiated
arguments. This model is cleaner, and works better for function
templates where the "final check" occurs during overload resolution.

Also, cope with cv-qualifiers when the parameter type was originally a
reference type, so that the deduced argument can be more qualified
than the transformed argument.
