Generate label string.  This may serve two use cases:
<ul>
<li>Generating operand label at markupAddress for referenced instruction and offcutAddress</li>
<li>Generating offcut label for an offcutAddress with instruction (markupAddress=null)</li>
</ul>
@param offcutAddress address for which generated label represents
@param instruction instruction containing offcut address
@param markupAddress address where a label will be referenced from (may be null)
@return generated offcut label
