Oh the non loop based slp, does not add alias checks. And you just enabled
that.

I think this is a won't fix as adding of aliasing checks for non loop based
slp, adds way too much overhead and might (will) be slower

I have to double check but the testcase might be hard to produce alias checks
too.
Marking the incoming arguments with restrict will also "fix" the code gen.

dst and src[12] alias but when you have the temporaries all reads happen before
the writes.
