The `test_do` CHECK block still passes when the compiler output omits the `private(...)` clause from `omp.wsloop`. The `test_begin_do` CHECK block has the same gap. Both tests would still pass if lowering omitted the private binding for the Fortran induction variable.

Could the `private(...)` checks require `Ei_private_i32` in two places: `test_do` and the selected branch of `test_begin_do`?
