[clang] [llvm] [StackProtector] Introduce stack-protect-attributor pass to remove unnecessary protections. (PR #150390)

Why is this a separate pass that removes attributes from the *function* if *all* allocas are safe, rather than integrated with the actual stack protection, so that the decision can be made per alloca?
