LoopVersioner changes for OffHeap support

Teaches LoopVersioner about dataAddr loads

Whenever we see a dataAddrPointer; all tests gets generated,
for null and array type, to use the child of the aloadi tree.

Fix `depsForLoopEntryPrep` tree pattern matching to allow for array
accesses to the 1st element using the dataAddrPointer, as that case
does not have an offset tree.

Fixing `requiresPrivatization()` to return false for dataAddr
nodes as they are internal-pointers.

Getting `childInRequiredForm` for the offheap case accessed the
wrong node with an extra `getFirstChild()` at the end.
