match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
mechanism. In the process, fix a bug where isinstance() and issubclass(),
when given a tuple of classes as second argument, were looking up
__instancecheck__ / __subclasscheck__ on the tuple rather than on each
type object.
Reviewed by Benjamin Peterson and Raymond Hettinger.
Add some test coverage to this code. More tests should be added (TODO added).

TESTED=./python -E -tt ./Lib/test/regrtest.py test_multiprocessing
* crashes on memory allocation failure found with failmalloc
* memory leaks found with valgrind
* compiler warnings in opt mode which would lead to invalid memory reads
* problem using wrong name in decimal module reported by pychecker
Update the valgrind suppressions file with new leaks that are small/one-time
leaks we don't care about (ie, they are too hard to fix).

At least some of these fixes should probably be backported to 2.5.

apply a patch for #3131. this solves the problem for the moment, but we should do some refactoring to get display logic out of RefactoringTool
