  New Revision: 48415

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=48415

  Log:
    insns.def (opt_succ): remove Time#succ optimization
    
    Time#succ is a deprecated method and not frequently used, so this wastes
    icache in vm_exec_core.  Using bloat-o-meter in the Linux kernel source
    to shows a small reduction on my x86-64 system:
    
    $ ~/linux/scripts/bloat-o-meter ruby.before ruby.after
    add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-57 (-57)
    function                                     old     new   delta
    vm_exec_core                               24216   24159     -57
    
    [Feature #10501]
