jeanPerier a527248a3c [flang][acc] allow and ignore DIR between ACC and loops (#106522) ...

The current pattern was failing OpenACC semantics in acc parse tree
canonicalization:

```
!acc loop
!dir vector aligned
do i=1,n
...
```

Fix it by moving the directive before the OpenACC construct node.

Note that I think it could make sense to propagate the $dir info to the
acc.loop, at least with classic flang, the $dir seems to make a
difference. This is not done here since few directives are supported
anyway.
