360db516cc Create stable metric to measure long computation in Const Eval 
This patch adds a `MirPass` that tracks the number of back-edges and
function calls in the CFG, adds a new MIR instruction to increment a
counter every time they are encountered during Const Eval, and emit a
warning if a configured limit is breached.

fd7a159710 Fix uninlined_format_args for some compiler crates 
Convert all the crates that have had their diagnostic migration
completed (except save_analysis because that will be deleted soon and
apfloat because of the licensing problem).

eb9e5e711d Auto merge of #105880 - Nilstrieb:make-newtypes-less-not-rust, r=oli-obk 
Improve syntax of `newtype_index`

This makes it more like proper Rust and also makes the implementation a lot simpler.

Mostly just turns weird flags in the body into proper attributes.

It should probably also be converted to an attribute macro instead of function-like, but that can be done in a future PR.

8bfd6450c7 A few small cleanups for newtype_index 
Remove the `..` from the body, only a few invocations used it and it's
inconsistent with rust syntax.

Use `;` instead of `,` between consts. As the Rust syntax gods inteded.

d679764fb6 Make #[debug_format] an attribute in newtype_index 
This removes the `custom` format functionality as its only user was
trivially migrated to using a normal format.

If a new use case for a custom formatting impl pops up, you can add it
back.

71ec1457ee Auto merge of #105436 - nnethercote:inline-place_contents_drop_state_cannot_differ, r=spastorino 
Inline and remove `place_contents_drop_state_cannot_differ`.

It has a single call site and is hot enough to be worth inlining. And make sure `is_terminal_path` is inlined, too.

Rollup merge of #105537 - kadiwa4:remove_some_imports, r=fee1-dead 
compiler: remove unnecessary imports and qualified paths

Some of these imports were necessary before Edition 2021, others were already in the prelude.

I hope it's fine that this PR is so spread-out across files :/

245c60749a Rewrite dest prop. 
This fixes a number of correctness issues from the previous version. Additionally, we use a new
strategy which has much better performance charactersitics and also finds more opportunities to
apply the optimization.
