[Bug tree-optimization/44468] Bogus access re-construction from offset calculation

[rguenth at gcc dot gnu dot org]

Argument why the testcase is invalid might go along the line that a pointer
to struct Q may not be converted to a pointer to struct R, or that
&((struct R *)q)->a is accessing *q as struct R.

This is similar to PR41317.
