Built-in function %ThrowTypeError% is incorrectly recognized as a constructor

[gibson042]

Environment: XS 11.6.0 32 4

Description

Steps to Reproduce

(function() {
  "use strict";

  const constructibles = [];
  if (isConstructible(Object.getOwnPropertyDescriptor(Function.prototype, "caller").get)) {
    constructibles.push(`Function.prototype "caller" getter`);
  }
  if (isConstructible(Object.getOwnPropertyDescriptor(Function.prototype, "arguments").get)) {
    constructibles.push(`Function.prototype "arguments" getter`);
  }
  if (isConstructible(Object.getOwnPropertyDescriptor(arguments, "callee").get)) {
    constructibles.push(`arguments "callee" getter`);
  }

  return constructibles;

  function isConstructible(fn) {
    try {
      Reflect.construct(function(){}, [], fn);
      return true;
    } catch (err) {
      return false;
    }
  }
})();

// => [`Function.prototype "caller" getter`, `Function.prototype "arguments" getter`, `arguments "callee" getter`]

Expected behavior
Output should be an empty array.

Other information
Per https://tc39.es/ecma262/#sec-built-in-function-objects , "Built-in function objects that are not identified as constructors do not implement the [[Construct]] internal method unless otherwise specified in the description of a particular function." There is no such specification at https://tc39.es/ecma262/multipage/ordinary-and-exotic-objects-behaviours.html#sec-%throwtypeerror% , so the %ThrowTypeError% built-in function should not have a [[Construct]] method and attempts to construct with it such as in the above code should fail with a TypeError exception per https://tc39.es/ecma262/multipage/reflection.html#sec-reflect.construct .

Thank you for the report. This one has an easy fix (don't set XS_CAN_CONSTRUCT_FLAG on %ThrowTypeError%. That will be in our next SDK update.
