Update based on further discussion with David Sankel.
* Rename `is_checkably_valid` to `detectably_invalid`
(with inverted return value)
* Ask LEWG to consider the alternative design that makes
`is_sufficiently_aligned` a nonmember function in `<bit>`
instead of a member function of `aligned_accessor`,
while LWG review of R2 proceeds concurrently
* P2389R2 was voted into the Working Draft at St. Louis,
so replace use of `dextents` in examples with `dims`.
* Minor formatting and non-wording fixes
Add non-wording section explaining why `aligned_accessor` has no `explicit` constructor from less to more alignment.
* Make is_sufficiently_aligned a nonmember function (in the wording) * Fix nonwording sections accordingly * Minor correction in Example in Wording * Update implementation Compiler Explorer link and source code (Appendix B)
* Improve Godbolt implementation I'm submitting P2897R4.html as P2897R4 (aligned_accessor).
* Move `is_sufficiently_aligned` from `<bit>` to `<memory>`, due to feedback from LEWG mailing list review of R4 * Give `is_sufficiently_aligned` a "*Throws*: Nothing" clause and add nonwording text explaining why
