<pre>All check-builtins tests were passing for me when I turned them on on macOS in
34b6f49c2ca4491a3a3ee520ea5919b8e7aeb459 / r371926.
Yesterday, my laptop auto-updated to Xcode 11 / 10.15 SDK, and now
clear_cache_test.c is failing (also when I sync my llvm checkout to known-good
34b6f49c2ca4491a3a3ee520ea5919b8e7aeb459):
