    fold-const: Return corresponding integral type for OFFSET_TYPE in
range_check_type [PR101162]

    Andrew's recent r12-1608-g2f1686ff70b25fceb04ca2ffc0a450fb682913ef change
    to fail verification on various unary and binary operations with
OFFSET_TYPE
    revealed that e.g. switchconv happily performs multiplications and
additions
    in OFFSET_TYPE.
