Rollup merge of #56699 - nnethercote:SymbolIndex, r=oli-obk 
Use a `newtype_index!` within `Symbol`.

This shrinks `Option<Symbol>` from 8 bytes to 4 bytes, which shrinks
`Token` from 24 bytes to 16 bytes. This reduces instruction counts by up
to 1% across a range of benchmarks.

cf47a19305 Bump to 1.33.0 
* Update bootstrap compiler
* Update version to 1.33.0
* Remove some `#[cfg(stage0)]` annotations

Actually updating the version number is blocked on updating Cargo

b4110900bd Update Cargo submodule and its dependencies 
Hopefully just another routine update!

So far this starts to enable the `std::arch` in stage0 builds of rustc.
This means that we may need stage0/not(stage0) in stdsimd itself, but
more and more code is starting to use `std::arch` so I think it's time
to start shifting the balance of work here.

4bb5d35659 Auto merge of #56392 - petrochenkov:regensym, r=oli-obk 
Delay gensym creation for "underscore items" (`use foo as _`/`const _`) until name resolution

So they cannot be cloned by macros. See https://github.com/rust-lang/rust/pull/56303 for the discussion.

Mostly fix cross-crate use of underscore items by inverting the "gensyms are lost in metadata" bug as described in https://github.com/rust-lang/rust/pull/56303#issuecomment-442464695.
Fix unused import warnings for single-segment imports (first commit) and `use crate_name as _` imports (as specified in https://github.com/rust-lang/rust/pull/56303#issuecomment-442274118).
Prohibit accidentally implemented `static _: TYPE = EXPR;` (cc https://github.com/rust-lang/rust/pull/55983).
Add more tests for `use foo as _` imports.

787959c20d Use Cow in Token::String. 
`Printer::word` takes a `&str` and converts it into a `String`, which
causes an allocation. But that allocation is rarely necessary, because
`&str` is almost always a `&'static str` or a `String` that won't be
used again.

This commit changes `Token::String` so it holds a `Cow<'static, str>`
instead of a `String`, which avoids a lot of allocations.

Use full name to identify a macro in a `FileName`.

Before this two macros with same name would be indistinguishable inside a `FileName`.  This caused a bug in incremental compilation (see #53097) since two different macros would map out to the same `StableFilemapId`.

Fixes #53097.

resolve: Relax shadowing restrictions on macro-expanded macros

Previously any macro-expanded macros weren't allowed to shadow macros from outer scopes.
Now only "more macro-expanded" macros cannot shadow "less macro-expanded" macros.
See comments to `fn may_appear_after` and added tests for more details and examples.

The functional changes are a21f6f588fc28c97533130ae44a6957b579ab58c and 46dd365ce9ca0a6b8653849b80267763c542842a, other commits are refactorings.
