Before range over integer, types2 leaves constant expression in RHS of non-constant shift untyped, so idealType do the validation to ensure that constant value must be an int >= 0. With range over int, the range expression can also be left untyped, and can be an negative integer, causing the validation false. Fixing this by relaxing the validation in idealType, and moving the check to Unified IR reader.
