Changing alignment from 8 to 16 is only a minor benefit, if any, for most
vector systems.  Changing alignment from 16 to 32 is very minor, due to cache
line alignment.  Anything above that has no benefit.

I would support making 32 the default alignment, since it does have measurable
benefits on existing systems with only minor memory usage.

Aligning to page size by default seems to be a bit extreme, especially since
the benefits would be limited to certain devices on embedded systems.
