Add all possible UndefinedBehaviorSanitizer flags in Clang

[mathbunnyru]

There are additional flags for Clang when running with UndefinedBehaviorSanitizer

https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html

-fsanitize=undefined: All of the checks listed above other than float-divide-by-zero, unsigned-integer-overflow, implicit-conversion, local-bounds, vptr and the nullability-* group of checks.

We should:

• either enable all additional flags, all comment why we didn't add them-
• add a link to docs
