* benchmark/bm_vm1_gc_wb_ary(_promoted).rb: separate fastpath and
slowpath for WB. Before this change bm_vm1_gc_wb_ary.rb tried to check the performance for WB slowpath (making a reference from oldobj to newobj). However, from Ruby 2.2, 3 GCs are needed to promote new objects because only 3 age objects are promted objects. To compare fastpath and slowpath, introduce new "promoted" version benchmark. bm_vm1_gc_wb_ary.rb is for fastpath and bm_vm1_gc_wb_ary_promoted.rb is for slowpath. * benchmark/bm_vm1_gc_wb_obj(_promtoed).rb: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49985 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
