fix: Recover from missing argument in call expressions
Previously, when parsing an argument list with a missing argument (e.g., `(a, , b)` in `foo(a, , b)`), the parser would stop upon an unexpected token (at the second comma in the example), resulting in an incorrect parse tree.
This commit improves error handling in such cases, ensuring a more accurate parse tree is built.

Prevent running some code if it is already in the map
I realized that a lot of duplicates were being run through this function. Might be better to prevent them from computing all the information if it's already in the cache.
r? `@notriddle`
Stop bailing out from compilation just because there were incoherent traits
fixes#120343
but also has a lot of "type annotations needed" fallout. Some are fixed in the second commit.
Reconstify `Add`
r? project-const-traits
I'm not happy with the ui test changes (or failures because I did not bless them and include the diffs in this PR). There is at least some bugs I need to look and try fix:
1. A third duplicated diagnostic when a consumer crate that does not have `effects` enabled has a trait selection error for an upstream const_trait trait. See tests/ui/ufcs/ufcs-qpath-self-mismatch.rs.
2. For some reason, making `Add` a const trait would stop us from suggesting `T: Add` when we try to add two `T`s without that bound. See tests/ui/suggestions/issue-97677.rs
Optimize input queries that take no arguments
There is no point in having a hashmap and extra lock for this, it is always only a single value. This might speed up some things by a tiny bit for our crate graph query.
Switch OwnedStore handle count to AtomicU32
This is already panics if overflowing a u32, so let's use the smaller int size to save a tiny bit of memory.
internal: Update rustc_pattern_analysis dependency
Just bumping the dependency, as I've been making API changes over on the rustc side. More API changes incoming in the coming weeks.
One benefit of this: we no longer abort in the `DeconstructedPat: Debug` impl, which means we can use `tracing` to investigate issues.
Actually abort in -Zpanic-abort-tests
When a test fails in panic=abort, it can be useful to have a debugger or other tooling hook into the `abort()` call for debugging. Doing this some other way would require it to hard code details of Rust's panic machinery.
There's no reason we couldn't have done this in the first place; using a single exit code for "success" or "failed" was just simpler. Now we are aware of the special exit codes for posix and windows platforms, logging a special error if an unrecognized code is used on those platforms, and falling back to just "failure" on other platforms.
This continues to account for `#[should_panic]` inside the test process itself, so there's no risk of misinterpreting a random call to `abort()` as an expected panic. Any exit code besides `TR_OK` is logged as a test failure.
As an added benefit, this would allow us to support panic=immediate_abort (but not `#[should_panic]`), without noise about unexpected exit codes when a test fails.
