Remove use of `Self: Sized` from libsyntax
The bound is not required for compiling but it prevents using `next_token()` from a trait object.
Fixes#33506.
rustc: Forbid `-Z` flags on stable/beta channels
First deprecated in rustc 1.8.0 the intention was to never allow `-Z` flags make
their way to the stable channel (or unstable options). After a year of warnings
we've seen one of the main use cases, `-Z no-trans`, stabilized as `cargo
check`. Otherwise while other use cases remain the sentiment is that now's the
time to start forbidding `-Z` by default on stable/beta.
Closes#31847

Run non-native tests on real device
After #40733, I've made some hacks to the QEMU client-server tools to allow running the tests on a real device when cross compiling Rust. The address and port of the remote server can be set using an environment variable.
I've made this mainly for local testing purposes, if you're interested in merging this, I'd clean it a bit more (eg. renaming the functions from `qemu-` to something else). I'm not asking for CI integration or adding ARM boards to the build system; it's just that I used these modifications and I was wondering if you'd find them useful too.
Remove obsolete --disable-elf-tls configure switch.
Support for disabling ELF-style thread local storage in
the standard library at configure time was removed in
pulls #30417 and #30678, in favour of a member in
the TargetOptions database. The new mentod respects
MACOSX_DEPLOYMENT_TARGET on macOS, addressing the
original use case for this configure optionl
However, those commits left the configure option itself
in place. It's no longer referenced anywhere and can
be removed.
Remove ast-ty-to-ty cache
As discussed on IRC, this basically just removes the cache, and rewrites rustdoc and save-analysis so call into the astconv code. It *might* make sense for this to be a more fine-grained query, but that would (at least) require us to be using `HirId` and not `NodeId`.
(Perhaps I should open a FIXME?)
I didn't measure perf impact (yet?). I did observe that the cache seems to hit *rarely* -- and only in between items (I experimented with a cache "per def-id", but that had zero hits). In other words, every single hit on the cache is a dependency bug, since it is "shuttling" information between items without dependency edges.

Fix @martinhath's mailmap entry
I stumbled upon a name duplication issue in [rust-lang-nursery/thanks](https://github.com/rust-lang-nursery/thanks/), and realized that this problem is easily fixable. I've (hopefully) done the right thing here. It works locally (`git shortlog | grep "Thoresen"` only returns one entry instead of two).
I didn't bother creating an issue in the `thanks` repository, since I did the `.mailmap` editing myself.
Generate XZ-compressed tarballs
Integrate the new `rust-installer` and extend manifests with keys for xz-compressed tarballs.

rustbuild: Sanity-check cmake for sanitizers too
It's possible to build the sanitizers when using an external LLVM, but
we still need cmake for this. Extend the sanity check to look for cmake
whenever sanitizers are enabled too.
