    debug/110295 - mixed up early/late debug for member DIEs

    When we process a scope typedef during early debug creation and
    we have already created a DIE for the type when the decl is
    TYPE_DECL_IS_STUB and this DIE is still in limbo we end up
    just re-parenting that type DIE instead of properly creating
    a DIE for the decl, eventually picking up the now completed
    type and creating DIEs for the members.  Instead this is currently
    defered to the second time we come here, when we annotate the
    DIEs with locations late where now the type DIE is no longer
    in limbo and we fall through doing the job for the decl.

    The following makes sure we perform the necessary early tasks
    for this by continuing with the decl DIE creation after setting
    a parent for the limbo type DIE.

            PR debug/110295
            * dwarf2out.cc (process_scope_var): Continue processing
            the decl after setting a parent in case the existing DIE
            was in limbo.

            * g++.dg/debug/pr110295.C: New testcase.
