[flang] change yielded iv value to be iv + step ( #174124 )
...
In cases where induction variables are used after the loop, like
```
write(*,*) (a(j),j=1,10)
print *, j
```
the incremented value should be used. Updating the FIRToSCF pass to
support this.

[Flang][Fir] Fix the comparison when lowering fir.iterate_while to scf.while. ( #171080 )
...
The comparison depends on the sign of the `step`, and when `step == 0` it always returns `false`.

[flang][fir] Convert fir.do_loop with the unordered attribute to scf.parallel. ( #168510 )

Refines the existing conversion to allow `fir.do_loop` annotated with
`unordered` to be lowered to `scf.parallel`, while other loops retain
their original lowering.

[flang][fir] Add FIR structured control flow ops to SCF dialect pass. ( #140374 )
...
This patch only supports the conversion from `fir.do_loop` to `scf.for`.
This pass is still experimental, and future work will focus on gradually
improving this conversion pass.
