Instead of instaling OCaml bindings in a location where installation
will not fail, don't build them in the first place.

…e visitors

In particular, use a blank visit_place for mutable visitor to be sure,
non modified visitors are not trying to mutating place.

This makes the note similar to the one found on rotate functions for
primitive types like i32/u32.

Prepare `MutVisitor`s to handle interned projections

The following are all the files where mir's `MutVisitor` is implemented. The `-` there stands for no changes, `visit_place` wasn't making any change on `Place`s. `x` stands for this file was changed to make `visit_place` do whatever it was doing with the base but avoid modifying the projection, instead just create a new one and assign to it.

There is some code repetition, just created the PR so we can start discussing it.

Disable Go and OCaml bindings when building LLVM

Instead of instaling OCaml bindings in a location where installation
will not fail, don't build them in the first place.

properly document panics in div_euclid and rem_euclid

For signed numbers, document that `div_euclid` and `rem_euclid` panic not just when `rhs` is 0, but also when the division overflows.

For unsigned numbers, document that `div_euclid` and `rem_euclid` panic when `rhs` is 0.

save-analysis: Nest tables when processing impl block definitions

Similar to rust-lang#65353 (which this PR should've been a part of), however in this case we didn't previously nest the tables when processing trait paths in impl block declarations.

Closes rust-lang#65411

reorder fmt docs for more clarity

I adjusted these docs in rust-lang#65332 but wasn't happy with the result when seeing it in rustdoc. So this reorders the subsections in the "Formatting Parameters" section to be more logical (subsections that reference `width` come after the `width` subsection) and they also all have examples now.

Fix left/right shift typo in wrapping rotate docs

Clarify diagnostics when using `~` as a unary op

It seems we prefer `bitwise not` to `bitwise negation`.
Fixes rust-lang#57239
