[analyzer] Fix handling of labels in getLValueElement
In getLValueElement Base may represent the address of a label
(as in the newly-added test case), in this case it's not a loc::MemRegionVal
and Base.castAs<loc::MemRegionVal>() triggers an assert, this diff makes
getLValueElement return UnknownVal instead.
