See bug. Medium-term, we might want to copy this dll to the build directory and
tweak rpaths – that's how we prevent reaching into the llvm build dir on mac.

I'm going to land this and see what happens. From my current understanding, it
shouldn't help with our asan bot (since that does a static library build, and
from my reading it looks like we link the asan runtime into the main executable
statically in this config, and statically link thunks into eventual other
non-component shared_libraries that delegate to the runtime in the main
executable – so that bot shouldn't need the asan dll from what I understand. But
this change is going to be needed for component builds anyhow, and maybe I'm
misunderstanding something and this does help after all. If it doesn't help,
I'll add `component=="shared_library"` to the conditional in a follow-up.)

LGTM

Probably we need to do the same trick for the ASan DLL thunk (static build)
