Create a similar rollup

In CI, the receiver thread can be descheduled for a surprisingly long time, so
there's no guarantee that a timeout actually occurs.
Avoid an ICE for:

    struct A;
    impl A<B> {}

The compiler no longer panics and can proceed to emit existing diagnostics.

Adds `tests/ui/missing/undeclared-generic-parameter.rs`.

Alternatively, I could split those out into a follow-up PR.~~ (Edit: will do in follow-up)

Remove a flaky `got_timeout` assert from two channel tests

In CI, the receiver thread can be descheduled for a surprisingly long time, so there's no guarantee that a timeout actually occurs.

One of these tests actually failed in rust-lang#153387 (comment).

Earlier failures:
- rust-lang#150365 (comment)
- rust-lang#147775 (comment)

diagnostics: avoid ICE for undeclared generic parameter in impl

Avoid an ICE for:

    struct A;
    impl A<B> {}

The compiler no longer panics and can proceed to emit existing diagnostics.

Adds `tests/ui/missing/undeclared-generic-parameter.rs`.

Fixes rust-lang#154165 and introduced by rust-lang#152913
…o_the_tracking_issue, r=JonathanBrouwer

Update the tracking issue for #[diagnostic::on_move]

PR rust-lang#150935 has been merged and then I have opened the tracking issue (whoops ?). So this update `compiler/rustc_feature/src/unstable.rs` to point to the right tracking issue.

This is related to the tracking issue rust-lang#154181

Log output for x86_64-gnu-aux has stalled, but that's not necessarily an indication that the job itself is stuck.

As usual, I'll give it until the 4 hour mark to finish.
