        <pre>I see the following bug at 95299019e35b (main from yesterday, 9/7).  git bisect
reveals it first appeared at a70ef3f568cb (a revert from Shilei on 7/15).  I am
testing while offloading from x86_64 to nvptx64.

```
$ cat test.c
include <stdio.h>
int main() {
  int x = 0, y = 1;
  #pragma omp target teams num_teams(1) map(tofrom:x, y)
  {
    x = 5;
    #pragma omp parallel num_threads(1)
    y = 6;
  }
  printf("%d, %d\n", x, y);
  return 0;
}
$ clang -fopenmp -fopenmp-targets=nvptx64 test.c
$ ./a.out
5, 1
```

I expect the output to be "5, 6".  It seems the parallel region does not
execute.</pre>
