Upstream for the sanitizers is located in LLVM compiler-rt/lib (it's
equivalent to libsanitier in GCC with added wrappers for GCC).

8snapshot contains a decent part of the upstreamed NetBSD work (at least
ASan, UBSan, partial TSan).

I think that we should upgrade libsanitizer to 8snapshot as-is, instead
of repeating the porting effort for 6.x. Or even better upgrade to HEAD
from LLVM directly (TSan, MSan + other fixes).

I will pickup the !amd64 patches added here and upstream to LLVM directly.
