Subject: * 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.
