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.

Detailed Description

This is an extension point for target-specific MCExpr subclasses to implement.

NOTE: All subclasses are required to have trivial destructors because MCExprs are bump pointer allocated and not destructed.
