Use `size_of_val` instead of manual calculation
Very minor thing that I happened to notice in passing, but it's both shorter and [means it gets `mul nsw`](https://rust.godbolt.org/z/Y9KxYETv5), so why not.
Fix generics mismatch errors for RPITITs on -Zlower-impl-trait-in-trait-to-assoc-ty
This PR stops reporting errors due to different count of generics on the new synthesized associated types for RPITITs. Those were already reported when we compare the function on the triat with the function on the impl.

Tweak implementation of overflow checking assertions
Extract and reuse logic controlling behaviour of overflow checking assertions instead of duplicating it three times.
r? `@cjgillot`
Previously, it would walk each directory twice: once in the main `Walk`
iterator, and once to count the number of entries in the directory. Now
it only walks each directory once.
- Skip files in `skip` wherever possible to avoid reading their contents
- Don't look for `tidy-alphabetic-start` in tests. It's never currently used and slows the check down a lot.
- Add new `filter_not_rust` helper function

resolve: Improve debug impls for `NameBinding`
Print at least the Some/None/Ok/Err status of the nested bindings if not the bindings themselves.
Noticed while reviewing https://github.com/rust-lang/rust/pull/108729.
Pass the right HIR back from `get_fn_decl`
Fixes#109232
Makes sure that the `fn_id: HirId` that we pass to `suggest_missing_return_type` matches up with the `fn_decl: hir::FnDecl` that we pass to it, so the late-bound vars that we fetch from the former match up with the types in the latter...
This HIR suggestion code really needs a big refactor. I've tried to do it in the past (a couple of attempts), but it's a super tangled mess. It really shouldn't be passing around things like `hir::Node` and just deal with `LocalDefId`s everywhere... Anyways, I'd rather fix this ICE, now.
Do not ICE for unexpected lifetime with ConstGeneric rib
Fixes#109143
r? ````@petrochenkov````
Combining this test with the previous test will affect the previous diagnostics, so I added a separate test case.
- only borrow the refcell once per loop
- avoid complex matches to reduce branch paths in the hot loop
- use a by-ref fast path that avoids mutations at the expense of having false negatives
Use index based drop loop for slices and arrays
Instead of building two kinds of drop pair loops, of which only one will be eventually used at runtime in a given monomorphization, always use index based loop.
Fix invalid markdown link references
Fixes invalid link references in librustdoc's template documentation.
`[text](link)` was interpreted as a relative path to the file, making the link invalid, while `[text][label]` references a label defined in the file itself: <https://www.markdownguide.org/basic-syntax/#reference-style-links>
Install projection from RPITIT to default trait method opaque correctly
1. For new lowering strategy `-Zlower-impl-trait-in-trait-to-assoc-ty`, install the correct default trait method projection predicates (RPITIT -> opaque). This makes default trait body tests pass!
2. Fix two WF-checking bugs -- first, we want to make sure that we're always looking for an opaque type in `check_return_position_impl_trait_in_trait_bounds`. That's because the RPITIT projections are normalized to opaques during wfcheck. Second, fix RPITIT's param-envs by not adding the projection predicates that we install on trait methods to make default RPITITs work -- I left a comment why.
3. Also, just a small drive-by for `rustc_on_unimplemented`. Not sure if it affects any tests, but can't hurt.

inherit_overflow: adapt pattern to also work with v0 mangling
This test was failing under new-symbol-mangling = true. Adapt pattern to work in both cases.
Related to #106002 from December.
