Subject: [PATCH 1/5] [flang][OpenMP] Try to unify induction var privatization
This PR tries to unify the paths taken by flang to privatize the
induction variable of loops. With the changes introduced here, both
cases below are now privatized in the same way:
```fortran
subroutine nested_constructs
implicit none
integer :: i
!$omp parallel default(private)
do i = 1, 10
end do
!$omp end parallel
end subroutine
```
```fortran
subroutine nested_constructs
implicit none
integer :: i
!$omp parallel private(i)
do i = 1, 10
end do
!$omp end parallel
end subroutine
```
