  New Revision: 41458

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=41458

  Log:
    * common.mk: add new rules `gcbench-rdoc', `gcbench-hash'.
    * tool/gcbench.rb: separate GC bench framework and process.
    * tool/hashbench1.rb, tool/hashbench2.rb: add two types GC bench.
      hashbench1: many temporal objects (GC by newobj)
      hashbench2: hash size becomes bigger and bigger (GC by malloc)
      Two benchs are executed by `gcbench-hash' rule.
    * tool/rdocbench.rb: separated.
