    compile.c: next label

    * compile.c (compile_next): label for jump to the end of block is
      removable.

    compile.c: remove more unreachable chunk

    * compile.c (remove_unreachable_chunk): remove beyond labels to be
      removed.

    compile.c: fix stack consistency error

    * compile.c (iseq_peephole_optimize): fix stack consistency error
      from return in loop, by adding extra `pop` when replacing `jump`
      with `leave`, which is never reached but needed to adjust sp
      calculation.  [ruby-core:84589] [Bug #14273]
