Bug 159899 – Make builtin TypeErrors consistent

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Joseph Pecoraro]

Summary:
Make builtin TypeErrors for |this| more consistent.

There have been multiple ways to report errors for non-coeracble this objects.

Approach 1:

>    if (this == null) {
>        if (this === null)
>            throw new @TypeError("X requires that |this| not be null");
>        throw new @TypeError("X requires that |this| not be undefined");
>    }

Approach 2:

>    if (this === null)
>        throw new @TypeError("X requires that |this| not be null");
>
>    if (this === @undefined)
>        throw new @TypeError("X requires that |this| not be undefined");

Approach 3:

>    if (this == null)
>        throw new @TypeError("X requires that |this| not be null or undefined");

Of these approaches, the last is the simplest, the smallest (half the byte code size), and provides the most useful information (lists all the values |this| cannot be). Lets converge on this approach.
