           Summary: [OpenMP] Fortran deep mapping of allocatable
                    components: Recursive types and FIRSTPRIVATE/PRIVATE
                    not handled

Testcase libgomp.fortran/map-alloc-comp-11.f90 - uses recursive types

Recursive types, i.e.
  type t
    type(t), allocatable :: next
  end type t

are not handled in with OpenMP's MAP clause

Additionally, while deep mapping works with the MAP clause, it does not work
with the FIRSTPRIVATE.

It likely also fails with PRIVATE and default initializers,
cf. PR 101602 comment 6 and PR 99519 for similar issues related to PRIVATE.
