* 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.
