Fix rust-lang#120186.
When a method not found on a type parameter could have been provided by any
of multiple traits, suggest each trait individually, instead of a single
suggestion to restrict the type parameter with *all* of them.

match lowering: consistently lower bindings deepest-first Currently when lowering match expressions to MIR, we do a funny little dance with the order of bindings. I attempt to explain it in the third commit: we handle refutable (i.e. needing a test) patterns differently than irrefutable ones. This leads to inconsistencies, as reported in rust-lang#120210. The reason we need a dance at all is for situations like: ```rust fn foo1(x: NonCopyStruct) { let y @ NonCopyStruct { copy_field: z } = x; // the above should turn into let z = x.copy_field; let y = x; } ``` Here the `y ````@````` binding will move out of `x`, so we need to copy the field first. I believe that the inconsistency came about when we fixed rust-lang#69971, and didn't notice that the fix didn't extend to refutable patterns. My guess then is that ordering bindings by "deepest-first, otherwise source order" is a sound choice. This PR implements that (at least I hope, match lowering is hard to follow 🥲). Fixes rust-lang#120210 r? ````@oli-obk```` since you merged the original fix to rust-lang#69971 cc ````@matthewjasper````

…, r=petrochenkov update indirect structural match lints to match RFC and to show up for dependencies This is a large step towards implementing rust-lang/rfcs#3535. We currently have five lints related to "the structural match situation": - nontrivial_structural_match - indirect_structural_match - pointer_structural_match - const_patterns_without_partial_eq - illegal_floating_point_literal_pattern This PR concerns the first 3 of them. (The 4th already is set up to show for dependencies, and the 5th is removed by rust-lang#116284.) nontrivial_structural_match is being removed as per the RFC; the other two are enabled to show up in dependencies. Fixes rust-lang#73448 by removing the affected analysis.

Follow up to rust-lang#120396, only last commit is relevant.
…ructors, r=dtolnay,oli-obk Make `NonZero` constructors generic. This makes `NonZero` constructors generic, so that `NonZero::new` can be used without turbofish syntax. Tracking issue: rust-lang#120257 ~~I cannot figure out how to make this work with `const` traits. Not sure if I'm using it wrong or whether there's a bug:~~ ```rust 101 | if n == T::ZERO { | ^^^^^^^^^^^^ expected `host`, found `true` | = note: expected constant `host` found constant `true` ``` r? `````@dtolnay`````
…ochenkov Switch OwnedStore handle count to AtomicU32 This is already panics if overflowing a u32, so let's use the smaller int size to save a tiny bit of memory.
