+Optional<uint64_t> APInt::tryZExtValue() const {
+  if (isSingleWord())
+    return Optional<uint64_t>(U.VAL);
+  return (getActiveBits() <= 64) ? Optional<uint64_t>(U.pVal[0])
+                                 : Optional<uint64_t>();
+}

----------------
These should just check for precondition and call the normal functions
