improves modref so it is almost able to remove the unnecesary stores to array
descriptors.  Unforutnately to elinate them one needs to handle the case that
calling unknown function is safe WRT all non-escaping values (since passing
them to the function makes them escape) that is sadly broken by Fortran FE
incorrectly annotating functions calling GOMP_parallel.
