[LLVMdev] [lld] buildbot configuration on using -fsanitize options

[Evgeniy Stepanov]

The bootstrap bot currently builds with libstdc++. AFAIU, lld does not
support that.
It would need to be switched to libc++. Also, MSan uses a precompiled,
instrumented libstdc++ binary, which should be replaced with libc++
built from source. We've got a script for it, which is not used at the
moment:

https://code.google.com/p/address-sanitizer/source/browse/trunk/build/scripts/slave/bootstrap/build_libcxx.sh

This looks like a non-trivial amount of work that I would be not have
time for in the near future.
You are welcome to try.
