	Try to evaluate the expression to the form (a - b + constant) where neither a nor b are variables.
MCFragment *	findAssociatedFragment () const
	Find the "associated section" for this expression, which is currently defined as the absolute section for constants, or otherwise the section associated with the first defined symbol in the expression.
