To compound this, BIGGEST_ALIGNMENT has effects beyond merely being an
upper bound of what alignment a target requires. Thus is cannot be
changed without breaking an ABI.
Thus I'm unwilling to lower this alignment unless you can promise
me that no vendor will ever introduce a new even wider vector type
on an existing architecture.
Or convince me I'm totally out to lunch with the issues here.
You're not, but I think it's about time that we ought to bite the bullet
and clean up the mess of multiple different uses of BIGGEST_ALIGNMENT
rather than constantly kludging around that mess.
