move MIR syntax into a dedicated file and ping some people whenever it changes
Adding or changing MIR operations/statements/whatever should be under significant scrutiny wrt their wider impact, specified semantics, and so on. So let's start by putting all that into a dedicated file and pinging some people whenever that file changes.
This PR only moves definitions around, and then fiddles with imports until it all works again.
Replace `sort_modules_alphabetically` boolean with enum
This fixes the long-standing FIXME there and makes the code easier to
understand. The reference to modules in both the old and new names seems
potentially wrong since I believe it applies to all items.

Make TAIT behave exactly like RPIT
fixes https://github.com/rust-lang/rust/issues/96552
This makes type-alias-impl-trait behave like return-position-impl-trait. Unfortunately it also causes some cases to stop compiling due to "needing type annotations" and makes panicking cause fallback for the hidden type to `()`.
All of these are addressable, but we should probably address them for RPIT and TAIT together

Avoid some `&str` to `String` conversions with `MultiSpan::push_span_label`
This patch removes some`&str` to `String` conversions with `MultiSpan::push_span_label`.
Unbreak stage1 tests via ignore-stage1 in `proc-macro/invalid-punct-ident-1.rs`.
#98188 broke `./x.py test --stage 1` (which I thought we ran in PR CI, cc `@rust-lang/infra)` i.e. the default `./x.py test` in dev checkouts, as the panic in `src/test/ui/proc-macro/invalid-punct-ident-1.rs` moved from the server (`rustc`) to the client (proc macro), and that means it's now affected by #59998.
I made the test look like `src/test/ui-fulldeps/issue-76270-panic-in-libproc-macro.rs` tho I'm a bit confused why that one is in `src/test/ui-fulldeps`, it should still work in `src/test/ui`, no? (cc `@Aaron1011)`
`alloc`: clean and ensure `no_global_oom_handling` builds are warning-free
Rust 1.62.0 introduced a couple new `unused_imports` warnings
in `no_global_oom_handling` builds, making a total of 5 warnings.

This PR cleans them and ensures no new ones are introduced
so that projects compiling `alloc` without infallible allocations
do not see them (and may want to enable `-Dwarnings`).
The couple `dead_code` ones may be reverted when some fallible
allocation support starts using them.

Triagebot: Fix mentions word wrapping.
I forgot that GitHub's markdown treats newlines as hard breaks. This was causing some ugly-looking word wrapping in the triagebot mention messages. This fixes it so that the lines are not hard-wrapped.
Ensure that `static_crt` is set in the bootstrapper whenever using `cc-rs` to get a compiler command line.
When attempting to build rustc with LLVM on Windows, I noticed that the CRT flag provided to the C and C++ Compilers was inconsistent:
```
"-DCMAKE_C_FLAGS=-nologo -MT -Brepro" "-DCMAKE_CXX_FLAGS=-nologo -MD -Brepro"
```
Since the bootstrapper also sets the various `LLVM_USE_CRT` variables, this resulted in cl.exe reporting a bunch of warnings:
```
cl : Command line warning D9025 : overriding '/MD' with '/MT'
```
The root cause for this is that `cc_detect::find` was creating a `cc::Build` twice, but didn't set `static_crt` the second time.
It's possible that this what is also causing #81381
emit Retag for compound types with reference fields
I want to add an option to Miri to do retagging inside reference fields. But that means we first have to even emit `Retag` for types that *contain* references (rather than being of reference types). :)
Stacked Borrows originally did that, but we stopped doing it when hitting bunch of issues in the standard library. However I have since realized that we actually do emit `noalias` for newtypes references, which means for soundness we should recurse into fields. Also it'd probably be bad news if newtypes lose out on optimizations (and they don't, for anything else). I want to add an option for that to Miri so that we can start experimenting with those semantics.

Clean up arg mismatch diagnostic, generalize tuple wrap suggestion
This is based on top of #97542, so just look at the last commit which contains the relevant changes.
1. Remove `final_arg_types` which was one of the last places we were using raw (`usize`) indices instead of typed indices in the arg mismatch suggestion code.
2. Improve the tuple wrap suggestion, now we suggest things like `call(a, b, c, d)` -> `call(a, (b, c), d)` 😺
3. Folded in fix#98645
