Currently, an error exists when InstrRefBasedLDV observes transfers of variables across copies, which causes it to lose track of variables under certain circumstances, resulting in shorter lifetimes for those variables as LDV gives up searching for live locations for them. This patch fixes this issue by storing the currently tracked values in the destination first, then updating them manually later without clobbering or assigning them the wrong value.
