ast: Avoid aborts on fatal errors thrown from mutable AST visitor Set the node to some dummy value and rethrow the error instead. When using the old aborting `visit_clobber` in `InvocationCollector::visit_crate` the next tests abort due to fatal errors: ``` ui\modules\path-invalid-form.rs ui\modules\path-macro.rs ui\modules\path-no-file-name.rs ui\parser\issues\issue-5806.rs ui\parser\mod_file_with_path_attr.rs ``` Follow up to https://github.com/rust-lang/rust/pull/91313. |

The rustc_ast crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).
For more information about how these things work in rustc, see the rustc dev guide:
