To fix both of these, instead of calling the native methods (in the scenario where the native methods behave incorrectly for negative and over-32-bit-length array-like objects), we need to reimplement all of them in their entirety. The ideal way to do this is to require in the implementations from the es5-shim, rather than duplicating all of the tests and code.
