Summary: frameobject.c cache friendliness patch

Initial Comment:
I was playing around with cachegrind, a cache profiler,
and noticed that some error checking code in
PyFrame_New generated quite a lot of cache misses.  

As the test is never going to pass without very dodgy C
code, I've moved it inside Py_DEBUG.

Hm. The type tests on code and back are clearly bogus, since
the variable types are already proof enough. So those can go
altogether.

For the rest I agree.
