Make this function work with signed integer types by extracting the
underlying type and finding the min and max values.
Change the signature to make it more consistent:
- The range is now given as an `Expr` in order to extract the type
- The container's path is now passed, and only as an `Option` so that
the function can be called in the general case without a container

`@rustbot` modify labels: rollup
Updates `interpret`, `codegen_ssa`, and `codegen_cranelift` to consume the new cast instead of the intrinsic.
Includes `CastTransmute` for custom MIR building, to be able to test the extra UB.
rustc has proper heuristics for actually checking whether a type allows
being left uninitialized (by asking CTFE). We can now use this for our
helper instead of rolling our own bad version with false positives.
Remove box expressions from HIR
After #108516, `#[rustc_box]` is used at HIR->THIR lowering and this is no longer emitted, so it can be removed.
This is based on top of #108471 to help with conflicts, so 43490488ccacd1a822e9c621f5ed6fca99959a0b is the only relevant commit (sorry for all the duplicated pings!)

Remove `identity_future` indirection
This was previously needed because the indirection used to hide some unexplained lifetime errors, which it turned out were related to the `min_choice` algorithm.
Removing the indirection also solves a couple of cycle errors, large moves and makes async blocks support the `#[track_caller]`annotation.
Fixes https://github.com/rust-lang/rust/issues/104826.
Migrate `write.rs` to `rustc_ast::FormatArgs`
changelog: none
Part 1 of #10233
The additions to `clippy_utils` are the main novelty of this PR, there's no removals yet since other parts still rely on `FormatArgsExpn`
The changes to `write.rs` itself are relatively straightforward this time around, as there's no lints in it that rely on type checking format params

Restrict `#[rustc_box]` to `Box::new` calls
Currently, `#[rustc_box]` can be applied to any call expression with a single argument. This PR only allows it to be applied to calls to `Box::new`
(This is a large commit. The changes to
`compiler/rustc_middle/src/ty/context.rs` are the most important ones.)
The current naming scheme is a mess, with a mix of `_intern_`, `intern_`
and `mk_` prefixes, with little consistency. In particular, in many
cases it's easy to use an iterator interner when a (preferable) slice
interner is available.
The guiding principles of the new naming system:
- No `_intern_` prefixes.
- The `intern_` prefix is for internal operations.
- The `mk_` prefix is for external operations.
- For cases where there is a slice interner and an iterator interner,
the former is `mk_foo` and the latter is `mk_foo_from_iter`.
Also, `slice_interners!` and `direct_interners!` can now be `pub` or
non-`pub`, which helps enforce the internal/external operations
division.
It's not perfect, but I think it's a clear improvement.
