Checks if (1-3) the underlying layout mapping map_ or (4-6) its type mapping_type models the semantics of LayoutMapping 's predicate mapping traits.

1-3) Let func be (1) is_unique , (2) is_exhaustive , or (3) is_strided , then it's equivalent to return map_. func ( ) ; .
4-6) Let func be (4) is_always_unique , (5) is_always_exhaustive , or (6) is_always_strided , then it's equivalent to return mapping_type :: func ( ) ; .
