Before, there was more or less duplicated suggestions to add type hints.
Fix by clearing more generic suggestions when a more specific suggestion
is possible.

This fixes rust-lang#93506 .

Fixes rust-lang#99089

In practice, this doesn't matter very much because the script takes ~no time to run.
But this makes `CARGO_LOG=info` easier to read, and theoretically saves a few milliseconds.

This makes `edition: 2021` work instead of the ugly
`edition:2021` one has to write.

Fix sized check ICE in asm check

Fixes (beta nominated, so doesn't close) rust-lang#99122

1. Moves a check for unresolved inference variables to _before_ other checks that could possibly ICE. We're not changing behavior here, just doing the same thing earlier in the function.
2. Erases region variables in sized check (which are not resolved at this point) because rustc will also ICE when region vars are passed to a query which does not canonicalize them.

Don't rerun the build script for the compiler each time on non-windows platforms

Do not error during method probe on `Sized` predicates for types that aren't the method receiver

Fixes rust-lang#61525

This is safe even though we're skipping an error because we end up confirming the method, which means we're still checking the `Sized` predicate in the end. It just means that we don't emit an erroneous message as below:

```
error: the `query` method cannot be invoked on a trait object
  --> src/lib.rs:14:11
   |
14 |         1.query::<dyn ToString>("")
   |           ^^^^^
   |
   = note: another candidate was found in the following trait, perhaps add a `use` for it:
           `use crate::Example;`
```

Also fixes erroneously suggesting the same trait over again, as seen in the `issue-35976.rs` UI test.
