7173712: G1: Duplicated code in G1UpdateRSOrPushRefOopClosure::do_oop_nv()
Summary: Duplicated code from G1RemSet::par_write_ref() inlined into G1UpdateRSOrPushRefOopClosure::do_oop_nv() was showing up in profiles with a fairly high amount of CPU time. Manually inline the main part of G1RemSet::par_write_ref() to eliminate the code duplication.
