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