    c++: Propagate TREE_ADDRESSABLE in fixup_type_variants [PR115062]

    This has caused issues with modules when an import fills in the
    definition of a type already created with a typedef.

            PR c++/115062

    gcc/cp/ChangeLog:

            * class.cc (fixup_type_variants): Propagate TREE_ADDRESSABLE.
            (finish_struct_bits): Cleanup now that TREE_ADDRESSABLE is
            propagated by fixup_type_variants.

    gcc/testsuite/ChangeLog:

            * g++.dg/modules/pr115062_a.H: New test.
            * g++.dg/modules/pr115062_b.H: New test.
            * g++.dg/modules/pr115062_c.C: New test.
