openacc: Fix race condition in Fortran loop collapse tests
The gangs participating in a gang-partitioned loop are not all guaranteed
to complete before some given gang continues to execute beyond that loop.
This means that two existing test cases contain a race condition,
because a loop that may be gang-partitioned is followed immediately by
another loop. The fix is to place the loops in separate parallel regions.
