LGTM - just simplify the shuffle masks (even if it break 80-col).

Please keep an eye out for any regressions, I'm not certain we've shaken out 
every possible issue.



================
Comment at: clang/lib/Headers/avx512fintrin.h:401
+  return __builtin_shufflevector(__a, __builtin_nondeterministic_value(__a), 0,
+                                 1, 2, 3, 4, 5, 6, 7);
 }
----------------
We don't always keep to clang formatting in the headers if it confuses things - 
better to keep the entire shuffle mask on a single line if possible - same for 
the others
```
  return __builtin_shufflevector(__a, __builtin_nondeterministic_value(__a),
                                 0, 1, 2, 3, 4, 5, 6, 7);
```

Comment at: clang/lib/Headers/avx512fintrin.h:409
+                                 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,
+                                 15);
 }
----------------
Maybe:
```
  return __builtin_shufflevector(__a, __builtin_nondeterministic_value(__a), 0,
                                 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 
14, 15);
```
