@eddyb indicated that alignment violating this check might be a bug. So let's see what the test suite says.

(Only the 2nd commit actually changes behavior... but I couldn't not do that other cleanup.^^)

Does the PR CI runner even enable debug assertions though...?

Oh, I see what's going on, one has to hide whitespace to review this PR.

Or just look at the 2nd commit. The first is a NOp but I couldn't resist doing the de-indentation when I noticed this...

Oh funny, we allow vectors with non-power-of-2 length? Interesting.
