Overall looks good to me, modulo the missing optional guard

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: swiftlang/swift-driver#2016. rdar://161721201

This sanitizer adds MTE (memory tagging extension) checks to stack variable accesses. It does not have a runtime library component, so some changes have been made to the driver logic to account for this cleanly.
