public Address getConstant(long val) {
		return new Address(constantspace, val);
	}
This routine encodes a specific value as a constant
address. I.e. the address space of the resulting Address
will be the constant space, and the offset will be the
value.
@param val is the constant value to encode
@return the constant address
