    To check magic LDC UDAs parameter types, convert them to their basetype first. (#1994)
    
    With this, you can check enums with Type::tint32, instead of constructing the enum type. For example: `checkStructElems(sle, {Type::tint32})` for this UDA:
    ```
    enum E {a,b,c};
    struct exampleUDA
    {
       E e;
    }
    ```
