out-of-range constants, because of the comments mentioned in #35753
    (except for enums, as apparently Delphi does the same)
  * added range check warnings about explicit type casts that throw away
    bits (e.g. byte($fff)), without giving warnings for most common cases
    (like cardinal(-1))
  * fixed masking/sign exting constant array indices (must be based on index
    range type size/signedness rather than on array size/"signedness")
