It is used and (un-)documented as OEP_ADDRESS_OF, see the ADDR_EXPR case:
case ADDR_EXPR:
return operand_equal_p (TREE_OPERAND (arg0, 0), TREE_OPERAND (arg1, 0),
TREE_CONSTANT (arg0) && TREE_CONSTANT (arg1)
? OEP_CONSTANT_ADDRESS_OF | OEP_ADDRESS_OF : 0);
So it's OEP_ADDRESS_OF but for constant addresses.
