replace llvm-rebuild-trigger with submodule commit hash
As mentioned in #59285.
This PR removes the need to update the `llvm-rebuild-trigger` file. Instead, the latest commit hash of the appropriate LLVM submodule will be stored in the stamp file and used to detect if a build is required.
Fixes#42405.
Fixes#54959.
Fixes#55537.
Use informational target machine for metadata
Since there is nothing to optimise there...
Should fix#58323 but haven’t tested locally.

Use 'write_all' instead of 'write' in example code
Using `write` without looping and checking the result can cause silent data loss. Example code should use `write_all` so that people don't copy this pattern. (Of course this does not include example code for docs that are specifically about the `write` method.)
Use `SmallVec` in `TokenStreamBuilder`.
This reduces by 12% the number of allocations done for a "clean incremental" of `webrender_api`, which reduces the instruction count by about 0.5%.

bootstrap: build crates under libtest with -Z emit-stack-sizes
Please see the comment in the diff for the rationale.
This change adds a `.stack_sizes` linker section to `libcompiler_builtins.rlib`
but this section is discarded by the linker by default so it won't affect the
binary size of most programs. It will, however, negatively affect the binary
size of programs that link to a recent release of the `cortex-m-rt` crate
because of the linker script that crate provides, but I have proposed a PR
(rust-embedded/cortex-m-rt#186) to solve the problem (which I originally
introduced :-)).
This change does increase the size of the `libcompiler_builtins.rlib` artifact we
distribute but the increase is in the order of (a few) KBs.

Combine all builtin late lints and make lint checking parallel
Blocked on https://github.com/rust-lang/rust/pull/57293.
Cuts runtime of late lint checking from 3.222s to 0.546s with 8 threads on `winapi` (@retep998 ;) )
r? @estebank
This reduces by 12% the number of allocations done for a "clean
incremental" of `webrender_api`, which reduces the instruction count by
about 0.5%.
It also reduces instruction counts by up to 1.4% across a range of
rustc-perf benchmark runs.

This commit removes the check that disallows the `#[non_exhaustive]`
attribute from being placed on enum variants and removes the associated
tests.
Further, this commit lowers the visibility of enum variant constructors
when the variant is marked as non-exhaustive.
