! This test checks lowering of OpenMP allocate Directive with align and allocator
! clauses to HLFIR. Verifies code generation for:
!   - align(16) only (null allocator)
!   - allocator(1) only (no align)
!   - align(64) allocator(6) (both clauses, array variable)
!   - align(32) allocator(3) (both clauses, multiple variables)
! Each omp.allocate_dir must be paired with a matching omp.allocate_free
