* 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

benchmark/bm_vm1_gc_wb_*.rb: fix GC.start args for invalid keyword "lazy_sweep" does not appear to have ever been a valid kwarg for GC.start, however the opposite of "lazy_sweep" appears to be "immediate_sweep". So use immediate_sweep, and flip the boolean value of each arg. I guess this only started failing with r56981 in Dec 2016 ("class.c: missing unknown_keyword_error", commit e3f0cca2f26ba44c810ac980cdff7dda129ae533) * benchmark/bm_vm1_gc_wb_ary.rb: "lazy_sweep: false" => "immediate_sweep: true" * benchmark/bm_vm1_gc_wb_ary_promoted.rb: ditto * benchmark/bm_vm1_gc_wb_obj.rb: ditto * benchmark/bm_vm1_gc_wb_obj_promoted.rb: ditto git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58565 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
