Rollup merge of #70857 - faern:use-assoc-int-float-consts, r=dtolnay 
Don't import integer and float modules, use assoc consts 2

Follow up to #70777. I missed quite a lot of places. Partially because I wanted to keep the size of the last PR down, and partially because my regexes were not good enough :)

Rollup merge of #70854 - faern:use-assoc-int-submodules, r=dtolnay 
Use assoc int submodules

Bumping some submodules to the commits their masters currently point at. The main point of this is to get the associated integer/float constant documentation updates that were recently merged to them:

* https://github.com/rust-lang/nomicon/pull/207
* https://github.com/rust-lang/rust-by-example/pull/1327
* https://github.com/rust-lang/stdarch/pull/848

But for some, a few more changes slipped by that happened to be in the master branch of these submodules.

Rollup merge of #70846 - tmiasko:compiler-builtins-codegen-units, r=alexcrichton 
Keep codegen units unmerged when building compiler builtins

Make it possible to control how mono items are partitioned into code generation
units, when compiling the compiler builtins, by retaining the original partitioning.

Helps with #48625, #61063, #67960, #70489.

Rollup merge of #70762 - RalfJung:miri-leak-check, r=oli-obk 
Miri leak check: memory reachable through globals is not leaked

Also make Miri memory dump prettier by sharing more code with MIR dumping, and fix a bug where the Miri memory dump would print some allocations twice.

Rollup merge of #70201 - cuviper:clone_into, r=dtolnay 
Small tweaks in ToOwned::clone_into

- `<[T]>::clone_into` is slightly more optimized.
- `CStr::clone_into` is new, letting it reuse its allocation.
- `OsStr::clone_into` now forwards to the underlying slice/`Vec`.

Speed up path searching with `find_library_crate`.

By doing prefix and suffix checking on a `String` copy of each relevant
`PathBuf`, rather than the `PathBuf` itself.

209b2be09f Auto merge of #70164 - eddyb:walk-generic-arg, r=nikomatsakis 
ty/walk: iterate `GenericArg`s instead of `Ty`s.

Before this PR, `Ty::walk` only iterated over `Ty`s, but that's becoming an increasing problem with `const` generics, as `ty::Const`s in `Substs` are missed by it.

By working with `GenericArg` instead, we can handle both `Ty`s and `ty::Const`s, but also `ty::Region`s, which used to require ad-hoc mechanisms such as `push_regions`.

I've also removed `TraitRef::input_types`, as it's both long obsolete, and easy to misuse.

f854070bb8 Forward OsStr::clone_into to the inner Vec 
Despite OS differences, they're all just `Vec<u8>` inside, so we can
just forward `clone_into` calls to that optimized implementation.

b80fa76ee0 Implement ToOwned::clone_into for CStr 
It can try to keep its allocation by converting the inner `Box` to
`Vec`, using `clone_into` on the bytes, then convert back to `Box`.

e8339e820b Use split_at in slice's ToOwned::clone_into 
It appears to codegen slightly more efficiently with `split_at` taking
two slices at once, rather than slicing across different calls.
