This extends llvm#138577 to more UBSan checks. Note that the annotations are less detailed: they will always be __ubsan_check_singularity, rather than using the SanitizerKind (previous behavior, which is not always possible for all UBSan checks) or SanitizerHandler. This is a (minor) regression compared to llvm#128977 and llvm#139809. Updates the tests from llvm#128976, llvm#139149 and llvm#141814.

This extends #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 #141814. --------- Co-authored-by: Vitaly Buka <[email protected]>
