The representation field of an inline class is not part of the generated code - it does not have a corresponding synthesized top-level methods like the other inline class members. Therefore, to support access to the representation field, a new `representationName` field is added to `InlineClass` that holds the name by which the representation field can be accessed. An access to the representation field is at runtime an access of the receiver itself. To show that the static type of the expression changes from the inline type of the receiver to the declared representation type, an `AsExpression` is inserted. Since this check is not needed at runtime, this node is marked with the new `isUnchecked` flag, that backends can use to skip the check.
