3fb27a0a9e Rollup merge of #42082 - michaelwoerister:wider_def_path_hashes, r=eddyb 
incr. comp.: Use more bits for DefPath hashes

Use 128 instead of 64 bits for DefPath hashes, like we do for everything else. Collision probability is unnecessarily high with 64 bits.

Also change the representation of `ich::Fingerprint` from `Fingerprint([u8; 16])` to `Fingerprint(u64, u64)` which is better for hashers like `FxHasher`.

rustbuild: install improvements

Install rust-analysis and rust-src to get in par with what we can get from rustup.
Allow bypassing the vendoring of dependencies. When we only build to install and not to redistribute dist tarballs, that part is not necessary, so avoid trying to install cargo-vendor.

Improve the error management when /proc is not mounted

This PR does two things:
* Triggers an error on GNU/Linux & Android when /proc/self/exe doesn't exist
* Handle the error properly

8292136fb0 Rollup merge of #41971 - japaric:pre-link-args, r=alexcrichton 
add -Z pre-link-arg{,s} to rustc

This PR adds two unstable flags to `rustc`: `-Z pre-link-arg` and `-Z
pre-link-args`. These are the counterpart of the existing `-C link-arg{,s}`
flags and can be used to pass extra arguments at the *beginning* of the linker
invocation, before the Rust object files are passed.

I have [started] a discussion on the rust-embedded RFCs repo about settling on a
convention for passing extra arguments to the linker and there are two options
on discussion: `.cargo/config`'s `target.$T.rustflags` and custom target
specification files (`{pre,,post}-link-args` fields). However, to compare these
two options on equal footing this `-Z pre-link-arg` feature is required.

[started]: https://github.com/rust-embedded/rfcs/pull/24

Therefore I'm requesting landing this `-Z pre-link-arg` flag as an experimental
feature to evaluate these two options.

ci: allows files to be shared by docker images

Change `src/ci/docker/run.sh` to allow files to be shared when building docker containers. For while, only android related shell scripts are shared. Others containers can be updated at any time.

sccache is installed last, as it is frequently updated this avoids the need to rebuilt the whole container.

Unify tools building

Close #41601

Time saving for up to 10 minutes. Cargo is now only compiled once.

Downsides:

- Out of tree Cargo.lock maintenance
- Cargo.toml `[replace]` version maintenance

4640e18572 Auto merge of #41911 - michaelwoerister:querify_trait_def, r=nikomatsakis 
Remove interior mutability from TraitDef by turning fields into queries

This PR gets rid of anything `std::cell` in `TraitDef` by
- moving the global list of trait impls from `TraitDef` into a query,
- moving the list of trait impls relevent for some self-type from `TraitDef` into a query
- moving the specialization graph of trait impls into a query, and
- moving `TraitDef::object_safety` into a query.

I really like how querifying things not only helps with incremental compilation and on-demand, but also just plain makes the code cleaner `:)`

There are also some smaller fixes in the PR. Commits can be reviewed separately.

0e79b9790a Unify all stage2 tools into a workspace 
This avoids double compiled Cargo. Hopefully this would speed up (extended) compilation for ~10m.

Notes: when updating Cargo submodule, the replacement version may also need to be updated.

* Triggers an error on GNU/Linux & Android when /proc/self/exe doesn't exist
* Handle the error properly

Fix #35829 (`quote!()` does not handle `br#"…"#`)

Fix issue #35829 (syntax extension's `quote_expr!()` does not handle `b"…"` and proc_macro's `quote!()` does not handle `r#"…"#`)

* Handles `b"…"`, `br#"…"#` and `...` for `quote_expr!()`.
* Refactored the match statement to allow it to complain loudly on any unhandled token.
* Similarly, proc_macro's `quote!()` did not handle `br#"…"#` or `r#"…"#`, so this PR fixes it too.
