This can happen when manually emitting strings into .drectve sections with `__attribute__((section(".drectve")))`, which is a way to emulate `#pragma comment(linker, "...")` for mingw compilers, without requiring building with -fms-extensions. Normally, this doesn't generate any comdat, but if compiled with -fsanitize=address, this section does get turned into a comdat section. This fixes #67261. This issue can be seen as a regression; a change in the "lli" tool in 17.x triggers this case, if compiled with ASAN enabled, triggering this unsupported corner case in LLD. With this change, LLD can handle it. (cherry picked from commit 503bc5f66111f7e4fc79972bb9bfec8bb5606bab)
