Remove the code from IVUsers that attempted to handle

casted induction variables in cases where the cast
isn't foldable. It ended up being a pessimization in

a bunch of complicated code in IVUsers' clients. The
advantages of this approach aren't visible enough to
justify it at this time.

- Register allocator should resolve the second part of the hint (register number) before passing it to the target since it knows virtual register to physical register mapping.
- More fixes to get ARM load / store double word working.
