    Integer literals are treated as constant values and are generally
    not included in data flow analyses and such, unlike Register and
    Op subclasses.

    Integer can represent multiple types:

     * Short tagged integers (short_int_primitive type; the tag bit is clear)
     * Ordinary fixed-width integers (e.g., int32_rprimitive)
     * Values of other unboxed primitive types that are represented as integers
       (none_rprimitive, bool_rprimitive)
     * Null pointers (value 0) of various types, including object_rprimitive
