  Log Message:
  -----------
  [asan][windows] When compiling with clang-cl or MSVC pass /Zl (that's a little L) (#85874)

/Zl is the equivalent of -nodefaultlibs. The idea here is to make sure
that the asan runtime doesn't have any defaultlibs directives, which
makes it easier to mix an asan runtime built with the dynamic CRT with
an application built with the static CRT (or vise-versa).

This is part of the overall effort to remove the static asan runtime on
windows entirely: https://github.com/llvm/llvm-project/pull/81677
