…target

It seems to apply to all doctests in the crate.

These are the rustdoc-wide options. It's easy to confuse them with
options for doctests in particular, so this change should help.

This fixes an issue when displaying on iPad, where the search box had no
borders.

Change default panic strategy to abort for wasm32-unknown-emscripten

Emscripten v2.0.10 removed __gxx_personality_v0 function stub that panic-unwind in wam32-unknown-emscripten target depends on. This causes linker error when using newer versions of emscripten compiler. As mentioned in rust-lang#85821 (comment) the __gxx_personality_v0 function was just a stub in emscripten for several years and therefor the panic-unwind strategy was broken all the time. Changing default to abort fixes builds  (issue 85821) with recent version of emscripten yet we are not loosing any functionality as the panic-unwind was broken anyway. Fixes  rust-lang#85821

Fix FIXME for `generic_arg_infer` in `create_substs_for_ast_path`

Fixes a FIXME, does some general refactoring of this fn, and also fixes a bug where we would use a const params defaults instead of an inference var ([playground](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=19456f65ea5dc3fcaa9b696f842ab380))

GATs outlives lint: Try to prove bounds

Fixes rust-lang#91036
Fixes rust-lang#90888
Fixes rust-lang#91348 (better error + documentation to be added to linked issue)

Instead of checking for bounds directly, try to prove them in the associated type environment.

Also, add a bit of extra information to the error, including a link to the relevant discussion issue (rust-lang#87479). That should be edited to include a brief summary of the current state of the outlives lint, including a brief background. It also might or might not be worth it to bump this to a full error code at some point.
