This is a reland of 24c626c1f7
Original change's description:
> Improve error messages for property access on null/undefined
>
> Only print the property name when accessing null/undefined if we can
> convert it to a string without causing side effects.
> If we can't, omit the property name in the error message.
> This should avoid confusion when the key is an object with toString().
> E.g. undefined[{toString:()=>'a'}] doesn't print 'read property [object
> Object]' anymore, which was misleading since the property accessed would
> be 'a', but we can't evaluate the key without side effects.

Tests that the peephole CompareEq optimization for the case where one side is predicted final object and the other side is predicted either final object or other (i.e. null or undefined) doesn't assert when the other side is also proven final object.
