4066c8ec71 Rollup merge of #41957 - llogiq:clippy-libsyntax, r=petrochenkov 
Fix some clippy warnings in libsyntax

This is mostly removing stray ampersands, needless returns and lifetimes. Basically a lot of small changes.

1940c31c92 Rollup merge of #41520 - estebank:trace-macro, r=nikomatsakis 
Use diagnostics for trace_macro instead of println

When using `trace_macro`, use `span_label`s instead of `println`:

```rust
note: trace_macro
  --> $DIR/trace-macro.rs:14:5
   |
14 |     println!("Hello, World!");
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: expands to `println! { "Hello, World!" }`
   = note: expands to `print! { concat ! ( "Hello, World!" , "\n" ) }`
```

Fix #22597.

bc259ee844 Introduce HirId, a replacement for NodeId after lowering to HIR. 
HirId has a more stable representation than NodeId, meaning that
modifications to one item don't influence (part of) the IDs within
other items. The other part is a DefIndex for which there already
is a way of stable hashing and persistence.

This commit introduces the HirId type and generates a HirId for
every NodeId during HIR lowering, but the resulting values are
not yet used anywhere, except in consistency checks.

9c15de4fd5 Auto merge of #40346 - jseyfried:path_and_tokenstream_attr, r=nrc 
`TokenStream`-based attributes, paths in attribute and derive macro invocations

This PR
 - refactors `Attribute` to use  `Path` and `TokenStream` instead of `MetaItem`.
 - supports macro invocation paths for attribute procedural macros.
   - e.g. `#[::foo::attr_macro] struct S;`, `#[cfg_attr(all(), foo::attr_macro)] struct S;`
 - supports macro invocation paths for derive procedural macros.
   - e.g. `#[derive(foo::Bar, super::Baz)] struct S;`
 - supports arbitrary tokens as arguments to attribute procedural macros.
   - e.g. `#[foo::attr_macro arbitrary + tokens] struct S;`
 - supports using arbitrary tokens in "inert attributes" with derive procedural macros.
   - e.g. `#[derive(Foo)] struct S(#[inert arbitrary + tokens] i32);`
where `#[proc_macro_derive(Foo, attributes(inert))]`

8d1c5700f0 Rollup merge of #40369 - petrochenkov:segspan, r=eddyb 
Give spans to individual path segments in AST

And use these spans in path resolution diagnostics.

The spans are spans of identifiers in segments, not whole segments. I'm not sure what spans are more useful in general, but identifier spans are a better fit for resolve errors.

HIR still doesn't have spans.

1b19284ad9 Auto merge of #40220 - jseyfried:ast_macro_def, r=nrc 
syntax: add `ast::ItemKind::MacroDef`, simplify hygiene info

This PR
 - adds a new variant `MacroDef` to `ast::ItemKind` for `macro_rules!` and eventually `macro` items,
 - [breaking-change] forbids macro defs without a name (`macro_rules! { () => {} }` compiles today),
 - removes `ast::MacroDef`, and
 - no longer uses `Mark` and `Invocation` to identify and characterize macro definitions.
   - We used to apply (at least) two `Mark`s to an expanded identifier's `SyntaxContext` -- the definition mark(s) and the expansion mark(s). We now only apply the latter.
