Ted Kremenek c1e4dd0e8e Change @import to @__experimental_modules_import. We are not ready to commit to a particular syntax for modules,
and don't have time to push it forward in the near future.

Douglas Gregor 540fd8135e When deserializing an anonymous namespace from a module, do not attach
the anonymous namespace to its parent. Semantically, this means that
the anonymous namespaces defined in one module are distinct from the
anonymous namespaces defined in another module.

Douglas Gregor 9b47f94133 Implement merging of namespace-scope declarations across modules, so
that we can merge, for example, two occurrences of

  namespace N { void f(); }

in two disjoint modules.

Douglas Gregor cfe7dc6b2f Implement redeclaration merging for namespaces defined in distinct
modules. Teach name lookup into namespaces to search in each of the
merged DeclContexts as well as the (now-primary) DeclContext. This
supports the common case where two different modules put something
into the same namespace.

Douglas Gregor e57e752b71 Switch NamespaceDecl from its own hand-rolled redeclaration chain over
to Redeclarable<NamespaceDecl>, so that we benefit from the improveed
redeclaration deserialization and merging logic provided by
Redeclarable<T>. Otherwise, no functionality change.

As a drive-by fix, collapse the "inline" bit into the low bit of the
original namespace/anonymous namespace, saving 8 bytes per
NamespaceDecl on x86_64.
