[WIP] Move even more early buffered lints to dyn lint diagnostics

[fmease]

Follow-up to #145881 and #145747.

TODO:

• Migrate most of if not the entire rest of the early buffered lints.
• Complete check-cfg migration if feasible or drop it for now (it's nasty due to it requiring a TyCtxt)
• Perf everything

• Complete check-cfg migration if feasible or drop it for now (it's nasty due to it requiring a TyCtxt)

Yeah, and it's even more complex as check-cfg lints are emitted from both rustc & rustdoc, which do not operate at the same time, rustc is at expansion time, while rustdoc is after expansion (and therefore has direct access to a TyCtxt).

[fmease]

The thing is, while currently only the post-expansion lint pass gets passed a TyCtxt (since your PR), in theory the pre-expansion lint pass has access to the TyCtxt, too, because both run inside create_and_enter_global_ctxt and TyCtxt::crate_name is already fed for the local crate (and I'm pretty decoding from metadata for foreign DefIds should also work inside the pre-expansion pass).

We can easily pass the TyCtxt to the pre-expansion pass that gets run on the root source file (crate root + inline modules) but the problem I was struggling with was passing the TyCtxt to the pre-expansion passes that get run for out-of-line/file modules because this happens in rustc_expand when expanding ModKind::Unloadeds where we only have access to an ExtCtxt¹ and a dyn LintStoreExpand but I'm not sure if it's sound (wrt. thread-local storage and query caching and maybe some other hidden assumptions²) to (make rustc_expand depend on rustc_middle and) store a TyCtxt inside ExtCtxt esp. once we parallelize things (CC #145354). That's where I gave up but I should probably just ping the relevant people.

Not being able to name TyCtxt inside rustc_attr_parsing shouldn't that huge of a problem, I'll just create a new proxy trait EarlyTyCtxt that defines crate_name similar to the LintEmitter and HirTyCtxt shenanigans we already have to do.

Footnotes

1. I still don't know what the Ext stands for. If it really does stand for extended then I must say that's a really non-descriptive name ^^' ↩

2. I really don't know what I'm talking about here btw. I know that both TyCtxt and ExtCtxt are !Send and !Sync so maybe everything is sufficiently locked down already? ↩

[fmease]

We can easily pass the TyCtxt to the pre-expansion pass

And I know we don't do that right now (we use Option<TyCtxt> as you know) but since I'm already trying to clean things up I was attempting to make TyCtxt unconditionally available to check-cfg. I don't remember if dropping that requirement I've imposed on myself makes the migration easier or not because we probably need to parametrize things over some proxy TyCtxt trait regardless.
