Fix TestEnumTypes.py for 32 bit platforms.

[amccarth]

Chaoren: Did this completely fix the test for you? It's still failing for me on Windows, but for a reason not addressed here.

We don't test host-only Windows. It's passing Windows to Android though.
What's the reason that it fails on Windows?

[amccarth]

The test expects expr *f.op to fail because f is a null pointer, but on Windows it yields (ops) $2 = 0. I suspect this is a latent expression evaluation bug exposed by the new test, as it also happens for other types of pointers and not just pointers to enums.
