[issue6292] Fix tests to work with -OO

[Collin Winter]

New submission from Collin Winter <collinw at gmail.com>:

The attached patch fixes a number of tests to work when -OO is given to 
Python. The majority of these tests are docstring-related, either doctests 
or making assertions about __doc__, with a handful of tests testing that 
assert statements will trigger and another handful of distutils tests that 
are looking for .pyc files.

With this applied, PYTHONOPTIMIZE=2 ./python.exe -OO Lib/test/regrtest.py 
now passes for trunk.
