Changes to iterator visualization motivated by visualization of
flat_meow:The visualizer for
_Deque_iteratorcan always detect== end()state since the iterator always has access to the underlying container. This is not always the case for_Span_iteratorand_Vector_iterator, but only at non-zero_ITERATOR_DEBUG_LEVEL.This PR adds a branch to the visualizer parsing logic to show the
endcondition at least in the debug build (which is most relevant for debugging after all).before:
