    * config/i386/i386.c (ix86_add_cfa_restore_note): Omit notes only
    if the function was not shrink-wrapped.
    (ix86_expand_epilogue): Ensure queued cfa_adjust notes are attached
    to an insn.
    * function.c (thread_prologue_and_epilogue_insns): Make sure the
    shrink_wrapped flag is set even if there is no dump file.
