changes: generate rcr retirehashtable code correctly according to the runtime interface.

TODO: Current implementation assumes that the size of the rcrRecord array is equal to the size of fsen.getDynamicInVarSet(). But, it seems not to be true since the rcrRecord array is allocated by the size of inset var which is actually related with coarse conflict.

Minor changes: Removing vestigial code

Previous commit:
-Every case where we enqueue an item will be guaranteed to have a case statement upon dequeue.
- Every valid pointer route will now end with either an enqueue to an array or Demsky's interface code with hashStructure.c
-Eliminated multiple traversals, empty switch statements and unused variables/pointers.
-Added new ArrayList based structure to store ObjRefs (only augmented by 1 method)

Added support for tracking which ConcreteRuntimeObjNodes can be Arrays and which can be array elements. Array elements get their own case statement since if we add the entire array into the queue, then it's probably better to let the switch statement handle what to do with objects from a specific allocation site.

I had more code written, but apparently my workspace was not up to date. The changes I made need changes, so I omitted them. It's okay since I need to ask Yonghun/Jim about arrays on the C-side anyway.
