Hi!

For these two, we need to actually map 3 things, the reference
(pointer-assign), the pointer (pointer-assign) and what the pointer points
to.

Testcase already in the testsuite, just needs non-shared address space.

Bootstrapped/regtested on x86_64-linux and i686-linux, committed to
trunk/4.9.

        * trans-openmp.c (gfc_omp_finish_clause): Handle scalar pointer
        or allocatable passed by reference.
        (gfc_trans_omp_clauses) <case OMP_LIST_MAP>: Likewise.
