bors 7349f6b503 Auto merge of #135057 - compiler-errors:project-unconstrained, r=oli-obk 
Project to `TyKind::Error` when there are unconstrained non-lifetime (ty/const) impl params

It splits the `enforce_impl_params_are_constrained` function into lifetime/non-lifetime, and queryfies the latter. We can then use the result of the latter query (`Result<(), ErrorGuaranteed>`) to intercept projection and constrain the projected type to `TyKind::Error`, which ensures that we leak no ty or const vars to places that don't expect them, like `normalize_erasing_regions`.

The reason we split `enforce_impl_params_are_constrained` into two parts is because we only error for *lifetimes* if the lifetime ends up showing up in any of the associated types of the impl (e.g. we allow `impl<'a> Foo { type Assoc = (); }`). However, in order to compute the `type_of` query for the anonymous associated type of an RPITIT, we need to do trait solving (in `query collect_return_position_impl_trait_in_trait_tys`). That would induce cycles. Luckily, it turns out for lifetimes we don't even care about if they're unconstrained, since they're erased in all contexts that we are trying to fix ICEs. So it's sufficient to keep this check separated out of the query.

I think this is a bit less invasive of an approach compared to #127973. The major difference between this PR and that PR is that we queryify the check instead of merging it into the `explicit_predicates_of` query, and we use the result to taint just projection goals, rather than trait goals too. This doesn't require a lot of new tracking in `ItemCtxt` and `GenericPredicates`, and it also seems to not require any other changes to typeck like that PR did.

UI Tests

This folder contains rustc's UI tests.

Test Directives (Headers)

Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and interpret a test.

As part of an ongoing effort to rewrite compiletest (see https://github.com/rust-lang/compiler-team/issues/536), a major change proposal to change legacy compiletest-style headers // <directive> to ui_test-style headers //@ <directive> was accepted (see https://github.com/rust-lang/compiler-team/issues/512.

An example directive is ignore-test. In legacy compiletest style, the header would be written as

// ignore-test

but in ui_test style, the header would be written as

//@ ignore-test

compiletest is changed to accept only //@ directives for UI tests (currently), and will reject and report an error if it encounters any comments // <content> that may be parsed as a legacy compiletest-style test header. To fix this, you should migrate to the ui_test-style header //@ <content>.
