Detailed Description

An abstract representation of an aligned address.

This is designed to be an IR-level abstraction, carrying just the information necessary to perform IR operations on an address like loads and stores. In particular, it doesn't carry C type information or allow the representation of things like bit-fields; clients working at that level should generally be using LValue. The pointer contained in this class is known to be unsigned.
