Ideally, all tests should pass on the platforms we build for. In your
case, it's not even very exotic, just x86_64 Linux. The LLVM and Clang
tests are pretty good in this regard, but various sanitizer and libc++
tests seem less stable. In practice, we've been releasing as long as
the failures don't look like regressions from previous releases.
