   A new clang version generally comes with bugfixes, new (sanitizer) features, and deprecations.

   Upgrade the sanitizer tasks to use the new version.

   This was also suggested in #31691 (comment)

   ACK fa5a02bcfa2f3769859332fddb8954d6217de7fc - tested 20 in some other infra, we just needed to fix the same deprecation warnings we’d seen, in cryptofuzz: https://github.com/fanquake/cryptofuzz/commit/09ca550c3ef7d6645869cb1ac014a4413d5388ba.
