Allow non-defining declarations of class template partial specializations to
...
have a nested name specifier. Strictly speaking, forward declarations of class
template partial specializations are not permitted at all, but that seems like
an obvious wording defect, and if we allow them without a nested name specifier
we should also allow them with a nested name specifier.

[modules] When parsing the base specifiers of a parse-merged class, the current
...
context is the class itself but lookups should be performed starting with the
lookup parent of the class (class and base members don't shadow types from the
surrounding context because they have not been declared yet).

[modules] When loading a template specialization, re-canonicalize its template

arguments because the reloaded form might have become non-canonical across the
serialization/deserialization step (this particularly happens when the
canonical form of the type involves an expression).

[modules] When performing redeclaration lookup for a using declaration, prefer
...
UsingShadowDecls over other declarations of the same entity in the lookup
results. This ensures that we build correct redeclaration chains for the
UsingShadowDecls (otherwise we could see assertions and other misbehavior in
modules builds, when merging combines multiple redeclaration chains for the
same entity from the same module into one chain).

[modules] Fix merging of default template arguments onto friend templates.
...
Previously we'd complain about redefinition of default arguments when we
instantiated a class with a friend template that inherits its default argument,
because we propagate the default template arguemnt onto the friend when we
reload the AST.
