`inspect.getmembers` is not fully tested

Bug report

Right now test_inspect checks getmembers with mostly classes and methods.
It does not test: function, traceback, code, frame, generator, coroutine, and builtin objects.
We should also test how predicate works for these objects.

However, they are listed in the docs: https://github.com/python/cpython/blob/a18c9854e8c255981f07c0a1c1503253f85b7540/Doc/library/inspect.rst#L47-L248

I will send a PR with new tests.
