Suggest adding a where-clause when that can help

Suggest adding a where-clause when there is an unmet trait-bound that can be satisfied if some type can implement it.

Fix LLVM assert when handling bad intrinsic monomorphizations

Passing an invalid type to certain intrinsics would trigger an LLVM assert even though the invalid type was caught by the compiler.

fce5901507 Rollup merge of #32679 - tclfs:patch-1, r=steveklabnik 
Remove error description of `move`

(1) `x` can be used in main() after the call to spawn(). Because the variables follow normal move semantics, though the keyword `move` is used, and i32 implements `Copy`.
(2) I remove this sentence because the previous sentence gives the referrence to `move closures`, and more description of `move` may be redundant.

Mention that it's not actually a data race

The example can't cause a data race since different indices are accesed.

(perhaps we should use an example where i iterates twice?)

af7b00b68f Rollup merge of #32682 - petrochenkov:field3, r=Manishearth 
The AST part of https://github.com/rust-lang/rust/pull/31937

Unlike HIR, AST still uses `Option` for field names because parser can't know field indexes reliably due to constructions like
```
struct S(#[cfg(false)] u8, u8); // The index of the second field changes from 1 during parsing to 0 after expansion.
```
and I wouldn't like to put the burden of renaming fields on expansion passes and syntax extensions.

[breaking-batch] Add support for `pub(restricted)` syntax in the AST

This PR allows the AST to represent the `pub(restricted)` syntax from RFC 1422 (cc #32409).

More specifically, it makes `ast::Visibility` non-`Copy` and adds two new variants, `Visibility::Crate` for `pub(crate)` and `Visitibility::Restricted { path: P<Path>, id: NodeId }` for `pub(path)`.

241a9d0ddf Auto merge of #32415 - alexcrichton:android-signal, r=alexcrichton 
std: Fix linking against `signal` on Android

Currently the minimum supported Android version of the standard library is
API level 18 (android-18). Back in those days [1] the `signal` function was
just an inline wrapper around `bsd_signal`, but starting in API level
android-20 the `signal` symbols was introduced [2]. Finally, in android-21
the API `bsd_signal` was removed [3].

Basically this means that if we want to be binary compatible with multiple
Android releases (oldest being 18 and newest being 21) then we need to check
for both symbols and not actually link against either.

This was first discovered in rust-lang/libc#236 with a fix proposed in
rust-lang/libc#237. I suspect that we'll want to accept rust-lang/libc#237 so
Rust crates at large continue to be compatible with newer releases of Android
and crates, like the standard library, that want to opt into older support can
continue to do so via similar means.

Closes rust-lang/libc#236

trans: don't declare symbols that were already imported.

Fixes #32740 by checking for a declaration before attempting a new one.
Before, `LLVMGetOrInsertFunction` was called for a existing import, but with a different type.
The returned value was a cast function pointer instead of a declaration, and we gave this
value to `llvm::SetFunctionCallConv` & friends , which triggered an LLVM assertion.
