  Log:
    compile.c: fix tailcall optimization
    
    * compile.c (iseq_peephole_optimize): don't apply tailcall
      optimization to send/invokesuper instructions with blockiseq.
      This is a follow-up to the changes in r51903; blockiseq is now
      the third operand of send/invokesuper instructions.
      [ruby-core:73413] [Bug #12018]
