This sanitizer adds MTE (memory tagging extension) checks to stack variable accesses. Enablement simply requires setting an attribute on function definitions, and the instrumentation is added by LLVM. The corresponding swift-driver change is at: https://github.com/swiftlang/swift-driver/pull/2016. rdar://161721201
