add is_sized method on Abi and Layout, and use it
This avoids the double negation of `!is_unsized()` that we have quite a lot.

Hash spans when interning types
Ignoring hash for spans creates an inconsistency between the `Hash` impl for `WithStableHash`, which takes them into account, and the `HashStable` impl which does not.

Resolve lifetimes independently for each item-like.
Now that the heavy-lifting is done on the AST and during lowering, we do not need to perform HIR lifetime resolution on a full item at once. Instead, we can treat each item-like independently, and look at `generics_of` the parent exceptionally for associated items.

Use `const_error_with_guaranteed` more
Better to pass down an ErrorGuaranteed rather than making a new one out of thin air, for some usages. Also for the ones where we *do* need to delay a bug, that delayed bug will have a more descriptive message.

Better error for HRTB error from generator interior
cc #100013
This is just a first pass at an error. It could be better, and shouldn't really be emitted in the first place. But this is better than what was being emitted before.

fix: lint against lint functions
Add `#[rustc_lint_diagnostics]` to lint functions missing them. From [this discussion](https://github.com/rust-lang/rust/pull/101138#issuecomment-1306379999).

selection failure: recompute applicable impls
The way we currently skip errors for ambiguous trait obligations seems pretty fragile so we get some duplicate errors because of this.
Removing this info from selection errors changes this system to be closer to my image of our new trait solver and is also making it far easier to change overflow errors to be non-fatal :sparkles:

resolve: More detailed effective visibility tracking for imports
Per-`DefId` tracking is not enough, due to glob imports in particular, which have a single `DefId` for the whole glob import item.
We need to track this stuff per every introduced name (`NameBinding`).
Also drop `extern` blocks from the effective visibility table, they are nominally private and it doesn't make sense to keep them there.
Later commits add some debug-only invariant checking and optimiaztions to mitigate regressions in https://github.com/rust-lang/rust/pull/103965#issuecomment-1304256445.
This is a bugfix and continuation of https://github.com/rust-lang/rust/pull/102026.
