Use inner iterator may_have_side_effect for Cloned
Previous implementation wasn't correct, as an inner iterator could have had side effects. Noticed by @bluss in #56534.
Added a bare-bones eslint config (removing jslint)
This change removes the small bit of jslint config, replacing it
with eslint. I've currently configured eslint to mostly only report
the more serious of lints, although there are still some style nits
turned on.
Eslint better supports modern js, and will be a good pre-TypeScript code
quality aid.
Install eslint with `npm install -g eslint`. Run with `eslint html/static/*.js`,
or let your IDE do it. This requires no build step.
Upcoming changes will start fixing identified bugs and other lints (mostly unused and var redef issues).
Fix invalid line number match
If a code line is longer than the width, it then gets to the next line making the line number not matching it anymore.

More MIR borrow check cleanup
* Fix some rustc doc links
* Remove the `region_map` field from `BorrowSet`
* Use `visit_local` to find 2PB activations

Add Weak.ptr_eq
I hope the doc tests alone are good enough.
We also might want to discuss the dangling pointer case (from `Weak::new()`).
Updates #55981.
Document `From` implementations
This PR is solves part of https://github.com/rust-lang/rust/issues/51430. It's my first PR, so I might need some guidance from @skade (as already mentioned in the issue).
The purpose of the PR is to document the `impl From` inside `path.rs` and answering the questions:
- What does it convert?
- Does it allocate memory?
- How expensive are the allocations?
I gave it a first shot, though an experienced rust developer might want to look over it.
emit error when doc generation fails
Fixes#41813.
The diagnostic looks something like this:
```
error: couldn't generate documentation: No space left on device (os error 28)

syntax: Use iterator and pattern APIs instead of `char_at`
Iterating over chars with the `char_at(str, i)` `i += ch.len_utf8()` loop seems unidiomatic.

Propagate all closure requirements to the caller
Closes#56477
This should be backported to 1.32 if it doesn't make the cut.

Instead of only determining whether some form of LTO is necessary,
determine whether thin, fat or no LTO is necessary. I've rewritten
the conditions in a way that I think is more obvious, i.e. specified
LTO type + additional preconditions.
This commit enables the Armv8-M Mainline architecture profile.
It adds two targets:
- thumbv8m.main-none-eabi
- thumbv8m.main-none-eabihf
The second one uses the Floating Point Unit for floating point
operations. It mainly targets the Cortex-M33 processor, which
can have the optional Floating Point Unit extension.
codegen_llvm_back: improve allocations
This commit was split out from https://github.com/rust-lang/rust/pull/54864. Last time it was causing an LLVM OOM, which was most probably caused by not collecting the globals.
- preallocate vectors of known length
- `extend` instead of `append` where the argument is consumable
- turn 2 `push` loops into `extend`s
- create a vector from a function producing one instead of using `extend_from_slice` on it
- consume `modules` when no longer needed
- ~~return an `impl Iterator` from `generate_lto_work`~~
- ~~don't `collect` `globals`, as they are iterated over and consumed right afterwards~~
While I'm hoping it won't cause an OOM anymore, I would still consider this a "high-risk" PR and not roll it up.
