This is quite hacky and I hope to refactor it a bit, but at least it
seems to work.

Clean up `ast::Attribute`, `ast::CrateConfig`, and string interning
This PR
- removes `ast::Attribute_` (changing `Attribute` from `Spanned<Attribute_>` to a struct),
- moves a `MetaItem`'s name from the `MetaItemKind` variants to a field of `MetaItem`,
- avoids needlessly wrapping `ast::MetaItem` with `P`,
- moves string interning into `syntax::symbol` (`ast::Name` is a reexport of `symbol::Symbol` for now),
- replaces `InternedString` with `Symbol` in the AST, HIR, and various other places, and
- refactors `ast::CrateConfig` from a `Vec` to a `HashSet`.

This allows you to enable *all* nested visits in a future-compatible
sort of way. Moreover, if you choose to override the `visit_nested`
methods yourself, you can "future-proof" against omissions by overriding
`nested_visit_map` to panic.

Basically adding `visit_impl_item` in various places and so forth.
|
|
This commit does not change how the incremental accounting is done, so
changes (or accessses) to an impl-item are still tagged to the enclosing
impl.
This commits adds the "main guts" of this change. It does not build on
its own.

This speeds up compilation by 3--6% across most of rustc-benchmarks.

std: Stabilize and deprecate APIs for 1.13
This commit is intended to be backported to the 1.13 branch, and works with the
following APIs:
Stabilized
* `i32::checked_abs`
* `i32::wrapping_abs`
* `i32::overflowing_abs`
* `RefCell::try_borrow`
* `RefCell::try_borrow_mut`
Deprecated
* `BinaryHeap::push_pop`
* `BinaryHeap::replace`
* `SipHash13`
* `SipHash24`
* `SipHasher` - use `DefaultHasher` instead in the `std::collections::hash_map`
module
Closes #28147
Closes #34767
Closes #35057
Closes #35070

Enforce the shadowing restrictions from RFC 1560 for today's macros
This PR enforces a weakened version of the shadowing restrictions from RFC 1560. More specifically,
- If a macro expansion contains a `macro_rules!` macro definition that is used outside of the expansion, the defined macro may not shadow an existing macro.
- If a macro expansion contains a `#[macro_use] extern crate` macro import that is used outside of the expansion, the imported macro may not shadow an existing macro.
This is a [breaking-change]. For example,
```rust
macro_rules! m { () => {} }
macro_rules! n { () => {
macro_rules! m { () => {} } //< This shadows an existing macro.
m!(); //< This is inside the expansion that generated `m`'s definition, so it is OK.
} }
n!();
m!(); //< This use of `m` is outside the expansion, so it causes the shadowing to be an error.
```

jonas-schievink:whats-a-pirates-favorite-data-structure, r=pnkfelix
Contains a syntax-[breaking-change] as a separate commit (cc #31645).nnAlso renames slice patterns from `PatKind::Vec` to `PatKind::Slice`.
|
|
This applies the HIR changes from the previous commits to the AST, and
is thus a syntax-[breaking-change]
Renames `PatKind::Vec` to `PatKind::Slice`, since these are called slice
patterns, not vec patterns. Renames `TyKind::Vec`, which represents the
type `[T]`, to `TyKind::Slice`. Renames `TyKind::FixedLengthVec` to
`TyKind::Array`.

We touch the krate to adjust the maps, but we don't expose that data
widely.
