Clang Ubsan negation and unsigned integer overflow warnings

As part of documenting the supported debugging/sanitizer builds, I've run them all through the paces with CI-Kit.
The Clang Ubsan builds reports several negation and unsigned integer overflow warnings.
These warnings are not necessarily bugs but may indicate reliance on implementation-specific, platform-specific, unspecified, or undefined behaviors.
These source lines correspond closely (but not exactly) with master as of today.
The full log (with warnings for third-party code and/or warnings already corrected) is available for context.
