Florian Hahn 0d61ffd350 [Loads] Support SCEVAddExpr as start for pointer AddRec. ...

Extend handling to support `%base + offset` as start for AddRecs in
isDereferenceableAndAlignedInLoop. This is done by adjusting AccessSize
by the offset and effectively checking if the full object starting from
%base to %base + offset + access-size is dereferenceable.
