0dfa6ff3be Avoid cycles from projection bounds
Only check the own predicates of associated types when confirming
projection candidates.
Also consider implied bounds when comparing trait and impl methods.

582ccec1c5 Remove predicates on associated types from traits

Rollup merge of #77514 - scottmcm:less-once-chain-once, r=estebank
Replace some once(x).chain(once(y)) with [x, y] IntoIter

Now that we have by-value array iterators that are [already used](25c8c53dd9/compiler/rustc_hir/src/def.rs (L305-L307))...

For example,
```diff
-        once(self.type_ns).chain(once(self.value_ns)).chain(once(self.macro_ns)).filter_map(|it| it)
+        IntoIter::new([self.type_ns, self.value_ns, self.macro_ns]).filter_map(|it| it)
```

1aaafac6ff Add support for cmse_nonsecure_entry attribute
This patch adds support for the LLVM cmse_nonsecure_entry attribute.
This is a target-dependent attribute that only has sense for the
thumbv8m Rust targets.

Rollup merge of #76711 - davidtwco:issue-51154-param-closure, r=estebank
diag: improve closure/generic parameter mismatch

Fixes #51154.

This PR improves the diagnostic when a type parameter is expected and a closure is found, noting that each closure has a distinct type and therefore could not always match the caller-chosen type of the parameter.

Rollup merge of #76973 - lzutao:unstably-const-assume, r=oli-obk
Unstably allow assume intrinsic in const contexts

Not sure much about this usage because there are concerns
about [blocking  optimization][1] and [slowing down LLVM][2] when using `assme` intrinsic
in inline functions.
But since Oli suggested in https://github.com/rust-lang/rust/issues/76960#issuecomment-695772221,
here we are.
