Currently all of the logic for deleting hung off uses, which PHI/switch/etc use, is in their classes. This adds a bit to Value which tracks whether that user had hung off uses, then User can be responsible for clearing them instead of the sub classes. Note, the bit used here was taken from NumOperands which was 30-bits. Given the reduction to 29 bits, and the average User being just over 100 bytes, a single User with 29-bits of num operands would need 50GB of RAM for itself so its reasonable to assume that 29-bits is enough for now. This is a step towards hiding all the hung off uses logic in the User.
