* cp/rtti.c (get_tinfo_decl): Don't call comdat_linkage.

        Do set DECL_COMDAT.
        (synthesize_tinfo_var): Take the public decl.
        (create_real_tinfo_var): Likewise.  Check DECL_COMDAT.
        (emit_tinfo_decl): Adjust.  Call import_export_decl.
        * cp/decl2.c (import_export_decl): Simplify tinfo decl handling.
        * config/mips/mips.c (mips_output_external): Don't do sdata
        optimization for a variable with DECL_COMDAT set.
