    Remove self-assign from make_invisible_and_set_new_height
    
    In https://sourceware.org/ml/gdb-patches/2019-07/msg00509.html, Jan
    pointed out that clang points out that
    make_invisible_and_set_new_height self-assigns "height".
    
    This patch fixes the bug by renaming the formal parameter.
