6323d9a45b Auto merge of #52355 - pietroalbini:zfeature, r=eddyb 
Add the -Zcrate-attr=foo unstable rustc option

This PR adds a new unstable option to `rustc`: `-Zcrate-attr=foo`. The option can be used to inject crate-level attributes from the CLI, and it's meant to be used by tools like Crater that needs to add their own attributes to a crate without changing the source code.

The exact reason I need this is to implement "edition runs" in Crater: we need to add the preview feature flag to every crate, and editing the crates' source code on the fly might produce unexpected results, while a compiler flag is more reliable.

Rollup merge of #52703 - ljedrz:vec_improvements, r=nikomatsakis 
Improve a few vectors - calculate capacity or build from iterators

Collecting from iterators improves readability and tailoring vector capacities should be beneficial in terms of performance.

9f79d2f86a Auto merge of #50997 - michaelwoerister:pre-analyze-filemaps, r=Mark-Simulacrum 
Make FileMap::{lines, multibyte_chars, non_narrow_chars} non-mutable.

This PR removes most of the interior mutability from `FileMap`, which should be beneficial, especially in a multithreaded setting. This is achieved by initializing the state in question when the filemap is constructed instead of during lexing. Hopefully this doesn't degrade performance.

a1f8a6ce80 Fix FileMap::line_begin_pos(). 
The method relied on the FileMap still being under construction in
order for it to do what the name promises. It's now independent of
the current state.

Add existential type definitions

Note: this does not allow creating named existential types, it just desugars `impl Trait` to a less (but still very) hacky version of actual `existential type` items.

Implement edition hygiene for keywords

Determine "keywordness" of an identifier in its hygienic context.
cc https://github.com/rust-lang/rust/pull/49611

I've resurrected `proc` as an Edition-2015-only keyword for testing purposes, but it should probably be buried again. EDIT: `proc` is removed again.
