Make `-Z time-passes` less noisy
- Add the module name to `pre_AST_expansion_passes` and don't make it a
verbose event (since it normally doesn't take very long, and it's
emitted many times)
- Don't make the following rustdoc events verbose; they're emitted many times.
+ build_extern_trait_impl
+ build_local_trait_impl
+ build_primitive_trait_impl
+ get_auto_trait_impls
+ get_blanket_trait_impls
- Remove the `get_auto_trait_and_blanket_synthetic_impls` rustdoc event; it's wholly
covered by get_{auto,blanket}_trait_impls and not very useful.
I found this while working on https://github.com/rust-lang/rust/pull/81275 but it's independent of those changes.
Make more traits of the From/Into family diagnostic items
Following traits are now diagnostic items:
- `From` (unchanged)
- `Into`
- `TryFrom`
- `TryInto`
This also adds symbols for those items:
- `into_trait`
- `try_from_trait`
- `try_into_trait`

Print failure message on all tests that should panic, but don't
Fixes#80861. Tests with the `#[should_panic]` attribute should always print a failure message if no panic occurs, regardless of whether or not an `expected` panic message is specified.
Refractor a few more types to `rustc_type_ir`
In the continuation of #79169, ~~blocked on that PR~~.
This PR:
- moves `IntVarValue`, `FloatVarValue`, `InferTy` (and friends) and `Variance`
- creates the `IntTy`, `UintTy` and `FloatTy` enums in `rustc_type_ir`, based on their `ast` and `chalk_ir` equilavents, and uses them for types in the rest of the compiler.
~~I will split up that commit to make this easier to review and to have a better commit history.~~
EDIT: done, I split the PR in commits of 200-ish lines each

Stabilize `Seek::stream_position` (feature `seek_convenience`)
Tracking issue: #59359
Unresolved questions from tracking issue:
- "Override `stream_len` for `File`?" → we can do that in the future, this does not block stabilization.
- "Rename to `len` and `position`?" → as noted in the tracking issue, both of these shorter names have problems (`len` is usually a cheap getter, `position` clashes with `Cursor`). I do think the current names are perfectly fine.
- "Rename `stream_position` to `tell`?" → as mentioned in [the comment bringing this up](https://github.com/rust-lang/rust/issues/59359#issuecomment-559541545), `stream_position` is more descriptive. I don't think `tell` would be a good name.
What remains to decide, is whether or not adding these methods is worth it.
The angle brackets were not rendered, so code like this:
some_func: for<'a> fn(val: &'a i32) -> i32
would be rendered as:
some_func: fn'a(val: &'a i32) -> i32
However, rendering with angle brackets is still invalid syntax:
some_func: fn<'a>(val: &'a i32) -> i32
so now it renders correctly as:
some_func: for<'a> fn(val: &'a i32) -> i32
-----
However, note that this code:
some_trait: dyn for<'a> Trait<'a>
will still render as:
some_trait: dyn Trait<'a>
which is not invalid syntax, but is still unclear. Unfortunately I think
it's hard to fix that case because there isn't enough information in the
`rustdoc::clean::Type` that this code operates on. Perhaps that case can
be fixed in a later PR.
Check for rmeta crates when getting existing crates from cache
This change makes sure to check for rmeta files when resolving crates instead of always going to disk in that case.
Use `reachable_as_bitset` to reuse a bitset from the traversal rather
than allocating it seprately. Additionally check if there are any
unreachable blocks before proceeding.
Trying to shrink_to greater than capacity should be no-op
Per the discussion in https://github.com/rust-lang/rust/issues/56431, `shrink_to` shouldn't panic if you try to make a vector shrink to a capacity greater than its current capacity.
Remove CACHE_KEY global
We realized in https://github.com/rust-lang/rust/pull/80914 that the cache handling (through a global) needed to be updated to make it much easier to handle.
r? `@jyn514`
Fixes#76267
When there is a single applicable method candidate, but its trait bounds
are not satisfied, we avoid saying that the method is "not found".
Insted, we update the error message to directly mention which bounds are
not satisfied, rather than mentioning them in a note.
Make weak item traversal deterministic
Fix#81296.
(No test added. The relevant test *is* ui/panic-handler/weak-lang-item.rs, and this change should make it less flaky.)
