<pre>When doing build of LLVM on Windows with CMAKE_LINKER set to lld-link, 3 tests
fail.
I don't immediately see how the failures are related to things building with
lld -- the test doesn't use lld.
Maybe the shared libasan linked by lld is missing symbols or something?
Full cmake invocation below.
