  Log Message:
  [flang] Fix element indexing in Destroy component deallocation

Derived type `Destroy` function does not take step into consideration
when indexing the component element for deallocation. This leads to
incorrect deallocation in case like:

module mod1
  type :: t
    real, allocatable :: r(:)
  end type
  subroutine do_smth(c)
    class(t), intent(out) :: c(:)
    do i = 1, size(c)
      if (allocated(c(i)%r)) then
        print*, i, 'not deallocated'
      end if
    end do
  end subroutine
end module

program test
  use mod1
  type(t) :: z(6)
  integer :: i
  do i = 1, 6
  end do
  call do_smth(z(::2))

Similar change was done in D142527
