Hi,

I'm trying to run MySQL with ASAN on Windows (we're already clean on Linux).
However, seemingly linking with LLD isn't automatic:

R:\ade\sesse\mysql\obj\mysql-test>"c:\Program Files\LLVM\msbuild-bin\cl.exe"
/nologo /c hello.cpp -fsanitize=address
R:\ade\sesse\mysql\obj\mysql-test>"c:\Program Files\LLVM\bin\lld-link.exe"
/out:hello.exe hello.obj
c:\Program Files\LLVM\bin\lld-link.exe: warning: hello.obj: undefined symbol:

c:\Program Files\LLVM\bin\lld-link.exe: warning: hello.obj: undefined symbol:

__asan_init
c:\Program Files\LLVM\bin\lld-link.exe: warning: hello.obj: undefined symbol:
__asan_version_mismatch_check_v8
error: link failed

I can link in clang_rt.asan-x86_64.lib manually by giving the path, and then
simple tests work, but anything that tries to do LoadLibrary dies, so I suppose
this is the wrong approach:

Shouldn't this go automatically? I can't find a way to link with cl.exe; on
Linux, I guess the clang driver with -fsanitize=address does magic behind the
scenes, but giving -fsanitize=address to lld-link seemingly isn't allowed.
