Scott McMurray	fe0c08a4f2	Make non-power-of-two alignments a validity error in Layout ... Inspired by the zulip conversation about how `Layout` should better enforce `size < isize::MAX as usize`, this uses an N-variant enum on N-bit platforms to require at the validity level that the existing invariant of "must be a power of two" is upheld. This was MIRI can catch it, and means there's a more-specific type for `Layout` to store than just `NonZeroUsize`.	2022-04-08 20:17:38 -07:00
