Matthias Krüger e42a3baba3 Rollup merge of #153324 - ZuseZ4:fix-ad-impl-parsing, r=oli-obk
fix autodiff parsing for non-trait impl

fixes: https://github.com/rust-lang/rust/issues/153322

@Sa4dUs Looks like we missed a case.
But also, going through the code, line 455 seems suspicious to me:
`Annotatable::AssocItem(d_fn, Impl { of_trait: false })`
Are we sure that this should always be an Impl, and never an impl of a trait?

The files here use the LLVM FileCheck framework, documented at https://llvm.org/docs/CommandGuide/FileCheck.html.

One extension worth noting is the use of revisions as custom prefixes for FileCheck. If your codegen test has different behavior based on the chosen target or different compiler flags that you want to exercise, you can use a revisions annotation, like so:

// revisions: aaa bbb
// [bbb] compile-flags: --flags-for-bbb

After specifying those variations, you can write different expected, or explicitly unexpected output by using <prefix>-SAME: and <prefix>-NOT:, like so:

// CHECK: expected code
// aaa-SAME: emitted-only-for-aaa
// aaa-NOT:                        emitted-only-for-bbb
// bbb-NOT:  emitted-only-for-aaa
// bbb-SAME:                       emitted-only-for-bbb
