Since these elements now use `white-space: pre-wrap` since
784665d4ce, it's fine to use newlines
for formatting, which is smaller and a bit less complicated.

llvm-16: Use Triple.h from new header location.
LLVM 16 has moved Triple.h from ADT and into TargetParser.
LLVM [landed a commit](62c7f035b4) this morning moving the header. This change should make rustc continue to build against LLVM main.
Fix problem noticed in PR106859 with char -> u8 suggestion
HN reader `@ayosec` noticed that my #106859 a few weeks back, malfunctions if you have a Unicode escape, the code suggested b'\u{0}' if you tried to use '\u{0}' where a byte should be, when of course b'\u{0}' is not a byte literal, regardless of the codepoint you can't write Unicode escapes in a byte literal at all.
My proposed fix here just checks that the "character" you wrote is fewer than 5 bytes, thus allowing \x7F and similar escapes but conveniently forbidding even the smallest Unicode escape \u{0} before offering the suggestion as before.
I have provided an updated test which includes examples which do and don't work because of this additional rule.
Mark 'atomic_mut_ptr' methods const
There's nothing that would block these methods from being const (just an UnsafeCell get), and it would be helpful for FFI interfaces in static contexts

Run the tools builder on all PRs
Previously, it would only run on changes to subtrees, submodules, or select directories. That made it so that changes to the compiler that broke tools would only be detected on a full bors merge. This makes it so the tools builder runs by default, making it easier to catch breaking changes to clippy (which was the most affected).

Split fn_ctxt/adjust_fulfillment_errors from fn_ctxt/checks
This is a follow-up from #106477, addressing a small number of the `FIXME`s that were added, by moving some functions into the new(er) `adjust_fulfillment_errors` module.
More cleanup is possible for this file (and I'll hopefully get around to doing some of that soon) but the very first thing is to just move these functions out.
There should be no "real" changes in this PR, besides minor adjustments to imports and the functions being transferred.
Turn projections into copies in CopyProp.
The current implementation can leave behind projections that are moved out several times.
This PR widens the check to turn such moves into copies: a move out of a projection of a copy is equivalent to a copy of the original projection.
Modify existing bounds if they exist
Fixes#107335.
This implementation is kinda gross but I don't really see a better way to do it.
This primarily does two things: Modifies `suggest_constraining_type_param` to accept a new parameter that indicates a span to be replaced instead of added, if presented, and limit the additive suggestions to either suggest a new bound on an existing bound (see newly added unit test) or add the generics argument if a generics argument wasn't found.
The former change is required to retain the capability to add an entirely new bounds if it was entirely omitted.

Fix suggestions rendering when the diff span is multiline
Fixes#92741
cc `@estebank`
I think, I finally fixed. I still want to go back and try to clean up the code a bit. I'm open to suggestions.
Some examples of the new suggestions:

3 - mut if true { true } else { false }
2 + if true { true } else { false }

```
Should we add a test to ensure this behavior doesn't disappear in the future?
Run `expand-yaml-anchors` in `x test tidy`
Previously, the pre-commit hook which runs `x test tidy` could pass only to have CI fail within the first 30 seconds. This adds about 30 seconds to `test tidy` (for an initial run, much less after the tool is built the first time) in exchange for catching errors in `.github/workflows/ci.yml` before they're pushed.
There is a distinction between running this on wasm and i686, even though they should be
identical. This technically is not _incorrect_, it's just an unexpected difference, which is
worth investigating, but not for correctness.
Since we're changing a bunch of stuff, necessary to remove some codegen tests
which look for specific things. Also attempting to restart a test which timed out, maybe due to
fastly failing?
