  [flang] TBAA for memory accesses of derived type values. (#68047)

Since HLFIR bufferization can introduce shallow copies of derived
type values we have to be careful not to treat these load/store
operations as data-only-accesses. If a derived type has descriptor
members, we attach any-access tag now.
