This submodule update reverts <https://reviews.llvm.org/D81803>. While that change is meant to fix a real bug, [LLVM PR42623], it caused new permission errors on Windows 7 that make it unable to build any archives. This is probably the same root cause as [LLVM PR48378]. Fixes rust-lang#81051. We'll file a new Rust issue to track the LLVM resolution. [LLVM PR42623]: https://bugs.llvm.org/show_bug.cgi?id=42623 [LLVM PR48378]: https://bugs.llvm.org/show_bug.cgi?id=48378 (cherry picked from commit 31814c4)
