test-suite has nothing to do with https://lab.llvm.org/buildbot/#/builders/24/builds/1003, we don't run the test-suit there, we build compiler with compiler.

And this report looks bogus. So asan is broken with your patch.

This explains how to reproduce, if you have aarch64 workstation https://github.com/google/sanitizers/wiki/SanitizerBotReproduceBuild

TLDR
`stage1 build all` builds regular clang from the HEAD, including your patch
`stage2/asan build` uses that clang from stage1 to build clang instrumented with asan, there is tblg gen stape in this build, and it uses just build clang_with_asan, and it produces false reports.
