    The following makes sure to, at early debug generation time, mangle
    symbols we eventually end up outputting during late finish.

            * dwarf2out.c (reference_to_unused): Make FUNCTION_DECL
            processing more consistent with respect to
            symtab->global_info_ready.
            (tree_add_const_value_attribute): Unconditionally call
            rtl_for_decl_init to do all mangling early but throw
            away the result if early_dwarf.

            * g++.dg/lto/pr96690_0.C: New testcase.
