+    llvm::MD5::MD5Result Hash;
----------------
Instead of MD5, can we use xxhash (or whatever the fastest hash algorithm in LLVM is these days)? I don't think we need a particular hash algorithm, so we might as well go with the fastest one we have (as long as it does a good job avoiding collisions, of course).
