<pre>Right now ASAN on Windows expects that you link with clang-cl
-fsanitize=address so that the driver would pass the right library names to the
linker. This was done in r189389 AFAICT.
This has the huge downside of being too difficult to get to work on projects
that link with link.exe directly (such as Firefox). I think a much better
approach would be to put the path to those libraries in a .drectve section to
pass it to the linker from within the obj file, to avoid needing to pass in the
libraries through the clang-cl driver.
I'm planning on doing this, any objections?</pre>
