2483d842fb Rollup merge of #48353 - michaelwoerister:monoitem-static-defid, r=eddyb 
Allow for instantiating statics from upstream crates

This PR makes the infrastructure around translating statics a bit more flexible so that it can also instantiate statics from upstream crates if the need arises. This is preparatory work for a MIR-only RLIBs prototype, where the instantiation of a `static` may be deferred until a leaf crate.

a1a1409647 Rollup merge of #48317 - ExpHP:unused-unsafe-is-no-fn, r=estebank 
unused_unsafe: don't label irrelevant fns

Fixes #48131

Diagnostic bugfix to remove an errant note.  Stops the search for an enclosing unsafe scope at the first safe fn encountered.

```rust
pub unsafe fn outer() {
    fn inner() {
        unsafe { /* unnecessary */ }
    }

    inner()
}
```

**Before:**

```
warning: unnecessary `unsafe` block
 --> src/main.rs:3:9
  |
1 | pub unsafe fn outer() {
  | --------------------- because it's nested under this `unsafe` fn
2 |     fn inner() {
3 |         unsafe { /* unnecessary */ }
  |         ^^^^^^ unnecessary `unsafe` block
  |
  = note: #[warn(unused_unsafe)] on by default
```

**After:**

```
warning: unnecessary `unsafe` block
 --> src/main.rs:3:9
  |
3 |         unsafe { /* unnecessary */ }
  |         ^^^^^^ unnecessary `unsafe` block
  |
  = note: #[warn(unused_unsafe)] on by default
```

b3f85fdf33 Rollup merge of #48258 - nrc:save-proc-nested, r=eddyb 
save-analysis: power through bracket mis-counts

Closes #47981

This is pretty unsatisfying since it is working around a span bug. However, I can't track down the span bug and it could be in the parser, proc macro expansion, the user macro, or Syn (or any other library that can manipulate spans). Given that user code can cause this error, I think we need to be more robust here.

mir: Gather move at SwitchInt, Assert terminators

Previously, `_1` was not marked as "definitely uninitialized" after a `switchInt(move _1)` terminator.

I think the same goes for the `assert` terminator.

Rollup merge of #48221 - rkruppe:improve-ctypes-lint, r=estebank 
Overhaul improper_ctypes output

This snowballed into a rather big set of improvements to the diagnostics of the improper_ctypes lint. See commits for details, including effects of each change on the `compile-fail/improper-ctypes.rs` test (now a UI test), which is pretty gnarly and hopefully not representative of real code, but covers a lot of different error cases.

Rollup merge of #48157 - scottmcm:try-for-each, r=dtolnay 
Add Iterator::try_for_each

The fallible version of `for_each` aka the stateless version of `try_fold`.  Inspired by @cuviper's comment in https://github.com/rust-lang/rust/pull/45379#issuecomment-338370020 as a more direct and obvious solution than `.map(f).collect::<Result<(), _>>()`.

Like `for_each`, no need for an `r` version thanks to overrides in `Rev`.

063deba92e Auto merge of #47799 - topecongiro:fix-span-of-visibility, r=petrochenkov 
Fix span of visibility

This PR

1. adds a closing parenthesis to the span of `Visibility::Crate` (e.g. `pub(crate)`). The current span only covers `pub(crate`.
2. adds a `span` field to `Visibility::Restricted`. This span covers the entire visibility expression (e.g. `pub (in self)`). Currently all we can have is a span for `Path`.

This PR is motivated by the bug found in rustfmt (https://github.com/rust-lang-nursery/rustfmt/issues/2398).

The first change is a strict improvement IMHO. The second change may not be desirable, as it adds a field which is currently not used by the compiler.
