This patch fixes `TargetOp::getInnermostCapturedOmpOp()` to avoid detecting as
captured by the top target construct other constructs nested inside of a loop.
This prevents the `omp.target` verifier from incorrectly flagging valid SPMD
loops, like in the following example:
```f90
subroutine foo(n)
implicit none
integer, intent(in) :: n
integer :: i, j
!$omp target teams distribute parallel do
do i=1,n
!$omp simd
do j=1,n
call bar()
enddo
enddo
end subroutine foo
```
