Fix a bug Joe found in DI: when exploding a copyaddr that is  loading from our current allocation, we'd sometimes add loads corresponding to the "assign" to the use list for this memory object.
Fix a bug Joe found in DI: when exploding a copyaddr that is 
loading from our current allocation, we'd sometimes add loads
corresponding to the "assign" to the use list for this memory
object.

No testcase as this will be tested by Joe's forthcoming patch
to produce more copyaddrs from silgen.
