RKSimon added inline comments.

Comment at: lib/Headers/avx512bwintrin.h:2045
{
- return (__mmask64) __builtin_ia32_kunpckdi ((__mmask64) __A,
- (__mmask64) __B);
+ return (__mmask64) (( __B & 0xFFFFFFFF) | ((__mmask64) __A << 32));
}
----------------
Is this right? The Intel docs says it should be:
```
k[31:0] := a[31:0]
k[63:32] := b[31:0]
k[MAX:64] := 0
```
Also, is the cast on __A necessary?
Same for the others.
