    Partial cherry-pick of 4dd13988c93c24ba3605f4b9cafc97515c34f2ac, just the RISC-V backend bits.
    
    commit 4dd13988c93c24ba3605f4b9cafc97515c34f2ac

        Automatic replacement of get_insns/end_sequence pairs
    
        This is the result of using a regexp to replace instances of:
    
          <stuff> = get_insns ();
          end_sequence ();
    
        with:
    
          <stuff> = end_sequence ();
    
        where the indentation is the same for both lines, and where there
        might be blank lines inbetween.
