When mentioning lifetimes, put either the trait ref or the self type closer to the lifetimes
...
When mentioning lifetimes, only invert wording between the expected trait and the self type when the self type has the vid.
This way, the lifetimes always stay close to the self type or trait ref that actually contains them.

Still not great, but good enough to land this PR.

say "the lifetime" instead of "some lifetime" when it feels right
...
In particular, when we want to indicate that there is a connection
between the self type and the other types.

make evaluation track whether outlives relationships mattered
...
Previously, evaluation ignored outlives relationships. Since we using
evaluation to skip the "normal" trait selection (which enforces
outlives relationships) this led to incorrect results in some cases.

Clearer later use messages for calls
...
Give a special message when the later use is from a call. Use the span
of the callee instead of the whole expression. For conflicting borrow
messages say that the later use is of the first borrow.
