Sorry Alexey, forgot to address this one.
Right now we support maps of patters like (you can find some of this patters in
the tests for map clause) `S.p1->p2->p3`, or `S.p[3][0:N]` where `S.p` is an
array of pointers. Each individual pointer requires its own map but have to be
bound by the runtime to the same base declaration `S` so that on the device the
code can properly dereference `S` to get to the pointers. This flag is used to
signal that.
