    c++: Fix ICE after ambiguous inline namespace reopen [PR94257]

    Following DR2061, 'namespace F', looks for 'F's inside inline namespace=
s.
    That can result in ambiguous lookups that we failed to diagnose early
enough,
    leading us to push a new namespace and ICE later.  Diagnose the ambigui=
ty
    earlier, and then pick one.

            * name-lookup.c (push_namespace): Triage ambiguous lookups that
            contain namespaces.=
