/*==============================================================================
 * FUNCTION:	TargetQueue::visit
 * OVERVIEW:	Visit a destination as a label, i.e. check whether we need to queue it as a new BB to create later.
 *				Note: at present, it is important to visit an address BEFORE an out edge is added to that address.
 *				This is because adding an out edge enters the address into the Cfg's BB map, and it looks like the
 *				BB has already been visited, and it gets overlooked. It would be better to have a scheme whereby
 *				the order of calling these functions (i.e. visit() and AddOutEdge()) did not matter.
 * PARAMETERS:	pCfg - the enclosing CFG
 *				uNewAddr - the address to be checked
 *				pNewBB - set to the lower part of the BB if the address
 *				already exists as a non explicit label (BB has to be split)
 * RETURNS:		<nothing>
