Feature problem: Top-level prototype assignment

[Yi2255]

Problem

A code generator using setPrototype may generate code that assigns a value to the top-level prototype.

Example

const v11 = { a: 1 };
const v20 = v11.__proto__;
const newProto = { b: 2 };
v20.__proto__ = newProto; //TypeError: Immutable prototype object 'Object.prototype' cannot have their prototype set

The problem is more likely to be reproduced with the following generators weighting.

Also a good point! I guess this is quite similar to issue #452 and the same fix should work here.

Yes, it's a category of issues. Thank you for your reply!
