Prevents terminal spam.

The test was using an internal feature which doesn't really matter, but
more importantly, we're now fatally exiting after the duplicate lang
item, so this tests nothing.

Ignoring unused bindings should be a determination made by a human, `rustfix` shouldn't auto-apply the suggested change.

Fix rust-lang#54196.

Expand the primary span of E0277 when the immediate unmet bound is not what the user wrote:

pattern_analysis: cleanup the contexts

This cleans up a bit the various `*Ctxt`s I had left lying around. As a bonus this made it possible to make `PatternColumn` public. I don't have a use for that yet but that could come useful.

`UsefulnessCtxt` looks useless right now but I'll be adding a field or two in subsequent PRs.

document `FromIterator for Vec` allocation behaviors

[t-libs discussion](https://rust-lang.zulipchat.com/#narrow/stream/259402-t-libs.2Fmeetings/topic/Meeting.202024-01-24/near/417686526) about rust-lang#120091 didn't reach a strong consensus, but it was agreed that if we keep the current behavior it should at least be documented even though it is an implementation detail.

The language is intentionally non-committal. The previous (non-existent) documentation permits a lot of implementation leeway and we want retain that. In some cases we even must retain it to be able to rip out some code paths that rely on unstable features.
