    Hello, why is asan_dll_thunk used for -shared in [CrossWindows.cpp](https://github.com/llvm/llvm-project/blob/main/clang/lib/Driver/ToolChains/CrossWindows.cpp#L192) ? [https://github.com/MicrosoftDocs/cpp-docs/blob/main/docs/sanitizers/asan-building.md](asan-building.md) from Microsoft suggests that this is the old way to do things.

Is there a way to `-lclang_rt.asan_dynamic-x86_64 -lclang_rt.asan_dynamic_runtime_thunk-x86_64` on Windows when building a DLL right now ? When I try I see that it still links clang_rt.asan_dll_thunk-x86_64.lib in addition to those 2 and a simple example crashes after `AddressSanitizer Init done`.
