Andrew Trick 6ecbeefd50 Add AccessedStorage::Tail access kind and remove more checks.
Distinguish ref_tail_addr storage from the other storage classes.

We didn't have this originally because be don't expect a begin_access
to directly operate on tail storage. It could occur after inlining, at
least with static access markers. More importantly it helps ditinguish
regular formal accesses from other unidentified access, so we probably
should have always had this.

At any rate, it's particularly important when AccessedStorage is
generalized to arbitrary memory access.

The immediate motivation is to add an AccessPath utility, which will
need to distinguish tail storage.

In the process, rewrite AccessedStorage::isDistinct. This could have a
large positive impact on exclusivity performance.
