    c++: variable partial spec redeclaration [PR113612]

    If register_specialization finds a previous declaration and throws the =
new
    one away, we shouldn't still add the new one to
    DECL_TEMPLATE_SPECIALIZATIONS.

            PR c++/113612

    gcc/cp/ChangeLog:

            * pt.cc (process_partial_specialization): Return early
            on redeclaration.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1y/var-templ85.C: New test.
