Log:
[x86] Add some tests for a common unpack pattern of vector shuffle that
has a remarkably unique and efficient lowering.
While we get this some of the time already, we miss a few cases and
there wasn't a principled reason we got it. We should at least test
this. v8 already has tests for this pattern.
