CheckAddressOfOperand - The operand of & must be either a function designator or an lvalue designating an object. If it is an lvalue, the object cannot be declared with storage class register or be a bit field. Note: The usual conversions are *not* applied to the operand of the & operator (C99 6.3.2.1p[2-4]), and its result is never an lvalue. In C++, the operand might be an overloaded function name, in which case we allow the '&' but retain the overloaded-function type.
