Rename a few tests to make tidy happier
A somewhat random smattering of tests that I have recently looked at, and thus had cause to research and write down the reason for their existence.
On implicit `Sized` bound on fn argument, point at type instead of pattern
Instead of
```
error[E0277]: the size for values of type `(dyn ThriftService<(), AssocType = _> + 'static)` cannot be known at compilation time

output

Clippy subtree update
r? `@Manishearth`
Really delayed sync (2 1/2 weeks), because of a `debug_assertion` we hit, and I didn't have the time to investigate earlier.
It would be nice to merge this PR with some priority, as it includes a lot of formatting changes due to the rustfmt bump.
Include Cargo.lock update due to Clippy version bump and ui_test bump in Clippy.
Separate collection of crate-local inherent impls from error tracking
#119895 changed the return type of the `crate_inherent_impls` query from `CrateInherentImpls` to `Result<CrateInherentImpls, ErrorGuaranteed>` to avoid needing to use the non-parallel-friendly `track_errors()` to track if an error was reporting from within the query... This was mostly fine until #121113, which stopped halting compilation when we hit an `Err(ErrorGuaranteed)` in the `crate_inherent_impls` query.
Thus we proceed onwards to typeck, and since a return type of `Result<CrateInherentImpls, ErrorGuaranteed>` means that the query can *either* return one of "the list inherent impls" or "error has been reported", later on when we want to assemble method or associated item candidates for inherent impls, we were just treating any `Err(ErrorGuaranteed)` return value as if Rust had no inherent impls defined anywhere at all! This leads to basically every inherent method call failing with an error, lol, which was reported in #127798.
This PR changes the `crate_inherent_impls` query to return `(CrateInherentImpls, Result<(), ErrorGuaranteed>)`, i.e. returning the inherent impls collected *and* whether an error was reported in the query itself. It firewalls the latter part of that query into a new `crate_inherent_impls_validity_check` just for the `ensure()` call.
This fixes#127798.
Fix cargo staging for run-make tests
Follow-up to https://github.com/rust-lang/rust/pull/130642#issuecomment-2366891866 to make sure that when
```
$ COMPILETEST_FORCE_STAGE0=1 ./x test run-make --stage 0
```
is used, bootstrap cargo is used in order to avoid building stage 1 rustc. Note that run-make tests are usually not written with `--stage 0` in mind and some tests may rely on stage1 rustc (nightly) behavior, and it is expected that some tests will fail under this invocation.
This PR also fixes `tool::Cargo` staging in compiletest when preparing for `run-make` test mode, by chopping off a stage from the `compiler` passed to `tool::Cargo` such that when the user invokes with stage `N`
```
./x test run-make --stage N
```
the `run-make` test suite will be tested against the cargo built by stage `N` compiler. Let's take `N=1`, i.e. `--stage 1`, without chopping off a stage, previously `./x test run-make --stage 1` will cause stage 1 rustc + std to be built, then stage 2 rustc, and cargo will be produced by the stage 2 rustc, which is clearly not what we want. By chopping off a stage, it means that cargo will be produced by the stage 1 rustc.

fix: Fix a bug in span map merge, and add explanations of how span maps are stored
Because it took me hours to figure out that contrary to common sense, the offset stored is the *end* of the node, and we search by the *start*. Which is why we need a convoluted `partition_point()` instead of a simple `binary_search()`. And this was not documented at all. Which made me make mistakes with my implementation of `SpanMap::merge()`.
The other bug fixed about span map merging is correctly keeping track of the current offset in presence of multiple sibling macro invocations. Unrelated, but because of the previous issue it took me hours to debug, so I figured out I'll put them together for posterity.
Fixes#18163.
fix: Fix name resolution when an import is resolved to some namespace and then later in the algorithm another namespace is added
The import is flagged as "indeterminate", and previously it was re-resolved, but only at the end of name resolution, when it's already too late for anything that depends on it.
This issue was tried to fix in https://github.com/rust-lang/rust-analyzer/pull/2466, but it was not fixed fully.
That PR is also why IDE features did work: the import at the end was resolved correctly, so IDE features that re-resolved the macro path resolved it correctly.
I was concerned about the performance of this, but this doesn't seem to regress `analysis-stats .`, so I guess it's fine to land this. I have no idea about the incremental perf however and I don't know how to measure that, although when typing in `zbus` (including creating a new function, which should recompute the def map) completion was fast enough.
I didn't check what rustc does, so maybe it does something more performant, like keeping track of only possibly problematic imports.
Fixes#18138.
Probably fixes#17630.
analysis-stats: respect `--disable-proc-macros` flag
I noticed that this flag wasn't being respected by `analysis-stats` when profiling proc macro expansion, so here's a small fix.
