Introduce new lists LeadingReads and TrailingWrites to remember implicit loads respectively implicit reads. These directly correspond to the generated scalar loads/stores at CodeGeneration at the beginning and ending of each ScopStmt. As a consequence, we can have a direct mapping of LoadInst/StoreInst to their explicit MemoryAccess instead of a list of MemoryAccesses.  As an internal restructuring, this patch should have no behavioral change.
