6cb28b6617 Ident::with_empty_ctxt -> Ident::with_dummy_span 
`Ident` has had a full span rather than just a `SyntaxContext` for a long time now.

67d6ce4206 syntax_pos: NO_EXPANSION/SyntaxContext::empty() -> SyntaxContext::root() 
For consistency with `ExpnId::root`.

Also introduce a helper `Span::with_root_ctxt` for creating spans with `SyntaxContext::root()` context

Rollup merge of #63586 - petrochenkov:nospanned, r=eddyb 
cleanup: Remove `Spanned` where possible

It generally only makes sense on enums, otherwise it's more convenient to "flatten" it by adding a span field to the struct it wraps.

Rollup merge of #63075 - RalfJung:deref-checks, r=oli-obk 
Miri: Check that a ptr is aligned and inbounds already when evaluating `*`

This syncs Miri with what the Nomicon and the Reference say, and resolves https://github.com/rust-lang/miri/issues/447.

Also this would not have worked without https://github.com/rust-lang/rust/pull/62982 due to new cycles. ;)

Rollup merge of #63499 - nikomatsakis:issuee-63388-async-fn-elision-self-mut-self, r=cramertj 
handle elision in async fn correctly

We now always make fresh lifetimne parameters for all elided
lifetimes, whether they are in the inputs or outputs. But then
we generate `'_` in the case of elided lifetimes from the outputs.

Example:

```rust
async fn foo<'a>(x: &'a u32) -> &u32 { .. }
```

becomes

```rust
type Foo<'a, 'b> = impl Future<Output = &'b u32>;
fn foo<'a>(x: &'a u32) -> Foo<'a, '_>
```

that could be boxed to fulfill the expectation, like in the following

e4756e6b07 clear in-scope lifetimes for nested items in HIR lowering 
This was causing us to incorrectly think the lifetimes were
already declared on the scope for the nested item, when in fact
they are not inherited.

`impl Trait` or anonymous closures.

Rollup merge of #63346 - RalfJung:zeroed-lint, r=eddyb 
Lint on some incorrect uses of mem::zeroed / mem::uninitialized

Cc https://github.com/rust-lang/rust/issues/62825 and https://internals.rust-lang.org/t/make-mem-uninitialized-and-mem-zeroed-panic-for-some-types-where-0-is-a-niche/10605

This does not yet handle `NonNull`/`NonZero*`, but it is a start.

I also improved some doc issues I hit on the way, and added a useful helper to `TyS`.

EDIT: I added the relnotes label mostly as a proposal -- I think this is worth mentioning, but leave the decision up to the release team.

8a068699a2 Auto merge of #63446 - Centril:refactor-lowering, r=oli-obk 
Refactor and categorize lowering wrt. items / exprs

Split lowering into more files along the lines of "expression related" and "item related".
Also refactor huge methods into smaller ones.

A next step might be to introduce "type related" and merge patterns and statements combined with expressions into "value related". There's still more work to do but the PR was getting too big :)
