ART: Fix Quick's DCE+GVN DCE_GVN does not take into account the following case: mov a, b ... mov c, b when optimization tries to replace a with c it must ensure that for all uses of a there is no new definition of c before use. Otherwise that use will incorrectly substituted with new c instead of original b.
