pengfei added inline comments.


================
Comment at: clang/lib/Headers/prfchwintrin.h:54
+#pragma clang diagnostic ignored "-Wcast-qual"
+  __builtin_prefetch ((const void*)__P, 1, 3 /* _MM_HINT_T0 */);
+#pragma clang diagnostic pop
----------------
Can we declare `__builtin_prefetch` to volatile one in Builtins.def:
```
BUILTIN(__builtin_prefetch, "vvCD*.", "nc")
```
