Brian Norman 75c6d06077 [FIR] Collect local properties for CFG analysis with a FIR visitor
When collecting local properties for property initialization analysis,
the nodes of the CFG were navigated. However, there are problems when
trying to determine what local properties are defined within do-while
loops. This is because the node order of a CFG does not always follow
the FIR structure order.

By converting the collector to a FIR visitor, we can maintain the
structural order needed for finding properties defined within do-while
loops. This does require some additional logic though to make sure we
do not navigate into elements which are not part of the original graph
navigation.
