  [OPENMP50]Add codegen for update clause in depobj directive.

Added codegen for update clause in depobj. Reads the number of the
elements from the first element and updates flags for each element in
the loop.
```
omp_depend_t x;
kmp_depend_info *base = (kmp_depend_info *)x;
intptr_t num = x[-1].base_addr;
kmp_depend_info *end = x + num;
kmp_depend_info *el = base;
do {
  el.flags = new_flag;
  el = &el[1];
} while (el != end);
```
