the `float-cmp` and `num-traits` libraries don't (yet) support f16. Turns out we didn't really need much from them, just the ulps check. I've adapted the ulps check from miri instead

relevant for the cranelift backend, possibly other cases/targets too

Fix pointer API to match what was stabilized

We can do swizzles for 24, 32, 48 and 64 byte vectors by stacking multiple TBL instructions. See https://godbolt.org/z/PE95nrqjj for a comparison of the generated assembly.

Optimize `swizzle_dyn` for AArch64 with N > 16

`From` impls were already provided for the normal AArch64 ACLE vector types, but not for the x2,x3,x4 tuples of ACLE vectors. Rectify that. Also provide impls for vectors of `f16`, as I noticed they were missing.

For symmetry with `Mask::first_set`

Add `Mask::last_set` method

…mpls Provide `From` impls for AArch64 ACLE tuple types.

…r=aDotInTheVoid,GuillaumeGomez Add paths for linked associated items rustdoc-json emits intra-doc links to associated items using the associated item's id. For external associated items, that id is not present in `index`, and it was also missing from `paths`. This PR backfills missing `paths` summaries for intra-doc link targets from the resolved page item and cached parent paths. Local targets are only added when already present in `index`, preserving jsondoclint's local-path invariant. Fixesrust-lang#152511

…up, r=GuillaumeGomez Bring runtime symbols statics on par with foreign functions This PR cleanups the `static` items path when checking the runtime symbols, and brings it on par with the foreign functions check. It also fixes a bug where static only reported the invalid lint and never the suspicious lint. Best reviewed commit by commit.

Remove the blanket `#![cfg_attr(test, allow(unused))]` from bootstrap - Originally added by rust-lang#138704 --- This blanket allow was hiding several unused imports and items in test-only code. It has been replaced with a number of narrower ensures. We can also drop the `pretty_assertions` dev-dependency, which turns out to have been unused.
