  Log Message:
  -----------
  [ubsan] Add more -fsanitize-annotate-debug-info checks (#141997)

This extends https://github.com/llvm/llvm-project/pull/138577 to more UBSan checks, by changing SanitizerDebugLocation (formerly SanitizerScope) to add annotations if enabled for the specified ordinals.

Annotations will use the ordinal name if there is exactly one ordinal specified in the SanitizerDebugLocation; otherwise, it will use the handler name.

Updates the tests from https://github.com/llvm/llvm-project/pull/141814.
