Add "memtag" sanitizer that detects and mitigates stack memory issues using armv8.5 Memory Tagging Extension. It is similar in principle to HWASan, which is a software implementation of the same idea, but there are enough differencies to warrant a new sanitizer type IMHO. It is also expected to have very different performance properties. The new sanitizer does not have a runtime library (it may grow one later, along with a "debugging" mode). Similar to SafeStack and StackProtector, the instrumentation pass (in a follow up change) will be inserted in all cases, but will only affect functions marked with the new sanitize_memtag attribute.
