new prototype-inheritance* tests have invalid expectations for primitive types

These tests expect things like:

inner.pageXOffset to have the inner prototype chain.  primitive types (number, string, etc.) are wrapped using the lexical global object (according to Adam at least), so these expectations are wrong.

Will fix.

Clearing flag. Wrong bug.

I see typeof returning:
number
object
boolean
function

It seems that number and boolean should be ignored by these tests.  But "function" is not a primitive type, correct?  That should still have the inner global object's prototype chain, no?

Yeah, you want "object" and "function".  Keep in mind that JavaScript is tricky and typeof null === "object", so you want to filter those out as well.
