It is supposed to be vectorized on targets w/o V4QImode support. Not sure if the list of targets that FAIL the testcase would be smaller if I change the scan to an explicit list of targets (x86)? Meanwhile just add more targets to the xfail -- it really is a missed optimization as I guess for example arm also has V4SImode. (I tried to fix the vectorizer to deal with vector types in the IL but failed to quickly handle it)
