Fix double handling in `collect_tokens` Double handling of AST nodes can occur in `collect_tokens`. This is when an inner call to `collect_tokens` produces an AST node, and then an outer call to `collect_tokens` produces the same AST node. This can happen in a few places, e.g. expression statements where the statement delegates `HasTokens` and `HasAttrs` to the expression. It will also happen more after #124141. This PR fixes some double handling cases that cause problems, including #129166. r? `@petrochenkov` |

This is serves as a collection of crashes so that accidental ICE fixes are tracked. This was formally done at https://github.com/rust-lang/glacier but doing it inside the rustc testsuite is more convenient.
It is imperative that a test in the suite causes an internal compiler error/panic or makes rustc crash in some other way. A test will "pass" if rustc exits with something other than 1 or 0.
When adding crashes from https://github.com/rust-lang/rust/issues, the
issue number should be noted in the file name (12345.rs should suffice)
and perhaps also inside the file via //@ known-bug #4321
If you happen to fix one of the crashes, please move it to a fitting
subdirectory in tests/ui and give it a meaningful name.
Also please add a doc comment at the top of the file explaining why
this test exists. :)
Adding
Fixes #NNNNN
Fixes #MMMMM
to the description of your pull request will ensure the
corresponding tickets will be closed automatically upon merge.
The ticket ids can be found in the file name or the known-bug annotation
inside the testfile.
