No progress, but I just filed https://bugs.llvm.org/show_bug.cgi?id=34324 so it hopefully won't get lost.

It looks like the tests are failing, but simple programs compiled with -fsanitize=address seem to work.  I haven't tested it extensively, though.

I'm not completely happy with the situation, as we also have some major problems with AddressSanitizer on FreeBSD 12.0 (though this isn't the fault of compiler-rt).  But there's no need to block the release for this.
