[Bug fortran/36076] New: Pointer intent(IN): Mark as const pointer

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Unless I'm mistaken, we never mark dummy pointers as "const" for the middle
end.
For

  subroutine sub(a)
    integer, pointer, intent(in) :: a

the C code would be "void sub(const int *a)". I think we miss the "const" in
the when creating the GIMPLE. In principle this "const" should also be applied
to other arguments which are have not the POINTER argument. (However, we need
to be careful as the front end might generate pointer assignments itself.)
