[PATCH] D52386: [Lexer] Add udefined_behavior_sanitizer feature

[Nico Weber via Phabricator via llvm-commits]

thakis added a comment.

Looks like this landed in b32d40417e25bad79e9b5bc0f0a29d7ba0222ad9 but the review feedback was never addressed.

With a more fine-grained thing, we could use this to add a compile-time error to libcxxabi for D97323 <https://reviews.llvm.org/D97323>.
