devel/llvm-devel: Update to a new snapshot

Fix build without FLANG (plist issue).

Fix LLDB build on non-CURRENT, I accidently committed the removal of
the workaround patch (which didn't work on i386) with an llvm13 update
in ef505eaca6425dd075e64e166f7be7a0ead3fa59. This snapshot includes
the correct fix from upstream.
