@Stovent
Implement carrying_add and borrowing_sub on signed numbers
1266099
@Stovent
Correct signed bit int documentation
5c69055
@Stovent
Remove too long example
b998d82
@cjgillot
Only keep one version of ImplicitSelfKind.
1d3aab7
@cjgillot
Use tcx.hir() utils for spans in MIR building.
520bee4 
This corrects the `span_with_body` in the case of closures, which was
incorrectly shortened to the `def_span`.
@cjgillot
Simplify MIR building entry.
7d0f244
@cjgillot
Compute explicit MIR params on THIR.
7999207
@cjgillot
Also compute implicit params in THIR.
e6cf3ec
@cjgillot
Shrink some visibilities.

Rollup merge of rust-lang#93873 - Stovent:big-ints, r=m-ou-se
33bc548 
Reimplement `carrying_add` and `borrowing_sub` for signed integers.

As per the discussion in rust-lang#85532, this PR reimplements `carrying_add` and `borrowing_sub` for signed integers.

It also adds unit tests for both unsigned and signed integers, emphasing on the behaviours of the methods.
@Dylan-DPC
Rollup merge of rust-lang#101086 - cjgillot:thir-param, r=oli-obk
dbcd465 
Compute information about function parameters on THIR

This avoids some manipulation of typeck results while building MIR.
@Dylan-DPC
Rollup merge of rust-lang#101455 - thomcc:why-is-this-here, r=jyn514
eb3b53f 
Avoid UB in the Windows filesystem code in... bootstrap?

This basically a subset of the changes from rust-lang#101171. I didn't think to look in src/bootstrap for more windows filesystem API usage, which was apparently a mistake on my part. It's kinda goofy that stuff like this is in here, but what are you gonna do, computers are awful.

I also added `winbase` to the `winapi` dep -- I tested this in a tmp crate but needed to add this to your Cargo.toml -- you `use winapi::stuff::winbase` in this function, but are relying on something else turning on that feature.
@rustbot rustbot added T-bootstrap Relevant to the bootstrap subteam: Rust's build system (x.py and src/bootstrap) T-compiler Relevant to the compiler team, which will review and decide on the PR/issue. T-libs Relevant to the library team, which will review and decide on the PR/issue. rollup A PR which is a rollup labels Sep 7, 2022
