New Revision: 131736

URL: http://llvm.org/viewvc/llvm-project?rev=131736&view=rev
Log:
If it is a copying load, the target and the src
pointers are not the same DSNode, they point to the
same DSNode, for which metadata is needed. Initialize
the metadata to be the type of the load/store. This 
should be correct, as all access were typesafe 
till now, as per the typesafe src pointer node.
