Refactored code for transfer functions for binary operators involving two LValues.

Fixed bug in transfer functions for sizeof(*); we were incorrectly evaluating to
a value of the wrong type.

Fixed bug in transfer functions for compound assignments where we did not properly
handle assignments involving dereferences of symbolic values.
