Vectorizer has trouble with vpmovmskb and store
Hi all,
I've run into a case where the optimizer seems to be having trouble doing
the "obvious" thing.
Consider this code:
```
define i16 @foo(<8 x i16>* dereferenceable(16) %egress, <16 x i8> %a0) {
%a1 = icmp slt <16 x i8> %a0, zeroinitializer
%a2 = bitcast <16 x i1> %a1 to i16
%astore = getelementptr inbounds <8 x i16>, <8 x i16>*
