rustdoc: render generic params & where-clauses of cross-crate assoc tys in impls
We used to only ever render generic parameters & where-clauses of cross-crate associated types when the item was located inside of a trait and we used to just drop them when it was inside of an impl block (trait or inherent).
Fixes#112904.

remove unused field
Followup to #104455. The field is no longer needed since ExtractIf (previously DrainFilter) doesn't keep draining in its drop impl.
`hir`: Add `Become` expression kind (explicit tail calls experiment)
This adds `hir::ExprKind::Become` alongside ast lowering. During hir-thir lowering we currently lower `become` as `return`, so that we can partially test `become` without ICEing.

Switch some more Steps to `builder.msg`
In particular, this hides compiletest suites under a dropdown - some builders are configured with `verbose-tests`, which makes the suites take up many thousands of lines.

doc: loongarch: Update maintainers
My colleague, `@zhaixiaojuan,` has been completely occupied with other matters and is no longer in charge of Rust. Consequently, I intend to update the maintainers in the platform documentation to avoid causing any disruptions for her and to ensure that relevant notifications regarding LoongArch are promptly directed to the appropriate developers.
Thanks your for contributions!

I have only optimized for walltime of those methods, I haven't tested whether it eliminates bounds checks when indexing into slices via things like `(0..slice.len()).step_by(16)`.
For non-incremental builds on Unix, currently all the thread names look
like `opt regex.f10ba03eb5ec7975-cgu.0`. But they are truncated by
`pthread_setname` to `opt regex.f10ba`, hiding the numeric suffix that
distinguishes them. This is really annoying when using a profiler like
Samply.
This commit changes these thread names to a form like `opt cgu.0`, which
is much better.
Currently there are two problems.
First, the CGUS don't end up in size order. The merging loop does sort
by size on each iteration, but we don't sort after the final merge, so
typically there is one CGU out of place. (And sometimes we don't enter
the merging loop at all, in which case they end up in random order.)
Second, we then assign names that differ only by a numeric suffix, and
then we sort them lexicographically by name, giving us an order like
this:
regex.f10ba03eb5ec7975-cgu.1
regex.f10ba03eb5ec7975-cgu.10
regex.f10ba03eb5ec7975-cgu.11
regex.f10ba03eb5ec7975-cgu.12
regex.f10ba03eb5ec7975-cgu.13
regex.f10ba03eb5ec7975-cgu.14
regex.f10ba03eb5ec7975-cgu.15
regex.f10ba03eb5ec7975-cgu.2
regex.f10ba03eb5ec7975-cgu.3
regex.f10ba03eb5ec7975-cgu.4
regex.f10ba03eb5ec7975-cgu.5
regex.f10ba03eb5ec7975-cgu.6
regex.f10ba03eb5ec7975-cgu.7
regex.f10ba03eb5ec7975-cgu.8
regex.f10ba03eb5ec7975-cgu.9
These two problems are really annoying when debugging and profiling the
CGUs.
This commit ensures CGUs are sorted by name *and* reverse sorted by
size. This involves (a) one extra sort by size operation, and (b)
padding the numeric indices with zeroes, e.g.
`regex.f10ba03eb5ec7975-cgu.01`.
(Note that none of this applies for incremental builds, where a
different hash-based CGU naming scheme is used.)

CI: do not run Bump dependencies workflow on forks
I haven't found a prettier way of doing this. We can possibly only use the condition on the `pr` job (to just disallow the creation of the PR), or only on the `not-waiting-on-bors` step, as if it doesn't run, the following job (probably) also shouldn't run.

Test the cargo args generated by bootstrap.py
I recommend reviewing this commit-by-commit using the instructions in https://rustc-dev-guide.rust-lang.org/git.html#moving-large-sections-of-code.
- Test cargo arguments passed by bootstrap.py
This moves a lot of code around, but the logic itself is not too terribly complicated.
- Move almost all logic in `def bootstrap` to the `RustBuild` class, to avoid mixing setting configuration with running commands
- Update various doctests to the new (more complete) RustBuild config. In particular, don't pretend that `bin_root` supports `build` being unset.
- Change `parse_args` not to use a global, to allow testing it
- Set BUILD_DIR appropriately so bootstrap.py doesn't panic because cargo isn't found
- Allow passing arguments to `bootstrap_test.py`
Previous, it used the built-in test runner, which doesn't support options unless they're manually passed in the script.
- Fix progress messages for configure in bootstrap_test.py
Before it would unconditionally print `configure-args = []`.

Revert "Structurally resolve correctly in check_pat_lit"
This reverts commit 54fb5a48b9. Also adds a couple of tests, and downgrades the existing `-Ztrait-solver=next` test to a known-bug.
Fixes#112993
Move windows-sys arm32 shim to c.rs
This moves the arm32 shim in to c.rs instead of appending to the generated file itself.
This makes it simpler to change these workarounds if/when needed. The downside is we need to exclude a couple of functions from being generated (see the comment). A metadata solution could help here but they'll be easy enough to add back if that happens.
