641606 - A bunch of prototype method don't throw when used as a constructor

Status: RESOLVED DUPLICATE of bug 202019

(Core :: JavaScript Engine, defect)

Test case
------------
new Array.prototype.slice;
------------
Same issue with String.prototype.slice.
Also, the error message for a couple of others isn't clear.
With Array.prototype.{map|forEach}, a TypeError is thrown when no argument is passed, however, when the right arguments are passed, no error is thrown.

This has been discovered thanks to test262 - Test S15.4.4.10_A5.7 "If property does not implement the internal [[Construct]] method, throw a TypeError exception"

For normative reference: ES5.1 section 15 Standard Built-in ECMAScript Objects:
"None of the built-in functions described in this clause that are not constructors shall implement the [[Construct]] internal method unless otherwise specified in the description of a particular function."
And in 11.2.2 The new Operator:
"If constructor does not implement the [[Construct]] internal method, throw a TypeError exception."

Reproducible: Always
