[New-bugs-announce] [issue35214] Get the test suite passing with clang Memory Sanitizer enabled

[Gregory P. Smith]

New submission from Gregory P. Smith <greg at krypto.org>:

clang's memory sanitizer (-fsanitize=memory) turns up useful problems in code.  I'm working on getting a CPython buildbot running it setup but would like our build to be cleaner to start with before I run that.

These are the initial fixes required for most of CPython to pass in an msan build.  We've been using these with our interpreters at Google.  (PR coming)
