@Override
	// overridden to use our potential alternate home address
	ProgramLocation getHomeLocation() {
		if (alternateHomeLocation != null) {
			return alternateHomeLocation;

		return super.getHomeLocation();
	}
Note: this is the same as {@link #VariableNameLocationDescriptor(ProgramLocation, Program)}
except that it allows you to specify an alternate home location.  This is useful for
finding references to function variable names from operand fields.
