According to [13.6.2](https://www.openmp.org/wp-content/uploads/OpenMP-API-Specification-6-0.pdf), allocate clause should be allowed in DO directive. But in Flang, the syntax,
```
!$omp do private(CCC, val) allocate(omp_large_cap_mem_alloc:CCC, val)
!$omp parallel do private(CCC, val) allocate(omp_high_bw_mem_alloc:CCC, val) shared(AAA,BBB,DDD)
```
Throws the below diagnostic.
```
error: ALLOCATE clause is not allowed on the DO directive
!$omp do private(CCC, val) allocate(omp_large_cap_mem_alloc:CCC, val)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
error: ALLOCATE clause is not allowed on the PARALLEL DO directive
!$omp parallel do private(CCC, val) allocate(omp_high_bw_mem_alloc:CCC, val) shared(AAA,BBB,DDD)
```

Happy to submit PR to enable the support for allocate in both parallel do and do directives if the issue seems legit.
