Description: Adds configure flags for msan and ubsan builds to make it easier to enable. These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this.. (cherry picked from commit 1584a00) Co-authored-by: Gregory P. Smith greg@krypto.org [Google LLC] https://bugs.python.org/issue35214
