validation: fix invalid-fn-ptr error message
https://github.com/rust-lang/rust/pull/82061 changed the code here to print an `ImmTy` instead of a `ScalarMaybeUninit`; that was an accident. So go back to printing a `ScalarMaybeUninit`.

avoid full-slicing slices
If we already have a slice, there is no need to get another full-range slice from that, just use the original.

Fix ES5 errors (IE11)
rustdoc is supposed to run on IE11 but someone reported me that it wasn't. I just confirmed it by using `es-check` with the `es5` option like this:
```
$ es-check es5 src/librustdoc/html/static/*.js
```
The PR fixes those issues and add CI checks to prevent regressions.
`@Mark-Simulacrum:` I added checks in the CI, but not sure if it's the correct way to do it. Any help on that side would be very appreciated!

Ensures `make` tests run under /bin/dash (if available), like CI, and fixes a Makefile
Note: This cherrypicks #81688 (`@pnkfelix)`
Updates `tools.mk` to explicitly require `SHELL := /bin/dash`, since CI uses `dash` but other environments (including developer local machines) may default to `bash`.
Replaces bash-specific shell command in one Makefile with a dash-compatible alternative, and re-enables the affected Makefile test.
Removes apparently redundant definition of `UNAME`.

32-bit ARM: Emit `lr` instead of `r14` when specified as an `asm!` output register.
On 32-bit ARM platforms, the register `r14` has the alias `lr`. When used as an output register in `asm!`, rustc canonicalizes the name to `r14`. LLVM only knows the register by the name `lr`, and rejects it. This changes rustc's LLVM code generation to output `lr` instead.

const_generics: Dont evaluate array length const when handling errors
Fixes#79518Fixes#78246
cc ````@lcnr````
This was ICE'ing because we dont pass in the correct ``ParamEnv`` which meant that there was no ``Self: Foo`` predicate to make ``Self::Assoc`` well formed which caused an ICE when trying to normalize ``Self::Assoc`` in the mir interpreter

Add match pattern diagnostics regression test
Closes#72377 by adding a regression test.
This test case fails on stable but now works on beta and nightly. It *should* have worked already for years, the crucial point whether it is mentioned that some uncovered patterns are not explicitly mentioned.
Suggest to create a new `const` item if the `fn` in the array is a `const fn`
Fixes#73734. If the `fn` in the array repeat expression is a `const fn`, suggest creating a new `const` item. On nightly, suggest creating an inline `const` block. This PR also removes the `suggest_const_in_array_repeat_expressions` as it is no longer necessary.
Example:
```rust
fn main() {
// Should not compile but hint to create a new const item (stable) or an inline const block (nightly)
let strings: [String; 5] = [String::new(); 5];
println!("{:?}", strings);
}
```
Gives this error:
```
error[E0277]: the trait bound `std::string::String: std::marker::Copy` is not satisfied
--> $DIR/const-fn-in-vec.rs:3:32
|
2 | let strings: [String; 5] = [String::new(); 5];
| ^^^^^^^^^^^^^^^^^^ the trait `std::marker::Copy` is not implemented for `String`
|
= note: the `Copy` trait is required because the repeated element will be copied
```
With this change, this is the error message:
```

Implement the precise analysis pass for lint `disjoint_capture_drop_reorder`
The precision pass for the lint prevents the lint from triggering for a variable (that was previously entirely captured by the closure) if all paths that need Drop starting at root variable have been captured by the closure.

[rustdoc-json] Make `header` a vec of modifiers, and FunctionPointer consistent
Bumps version number and adds tests, this is a breaking change. I can split this into two (`is_unsafe` -> `header` and `header: Vec<Modifiers>`) if desired.
Rationale: Modifiers are individual notes on a function, it makes more sense for them to be a list of an independent enum over a String which is inconsistently exposing the HIR representation (prefix_str vs custom literals).
Function pointers currently only support `unsafe`, but there has been talk on and off about allowing them to also support `const`, and this makes handling their modifiers consistent with handling those of a function, allowing better shared code.

Updated smallvec version due to RUSTSEC-2021-0003
Hi.
Updated Cargo.toml's for smallvec due to RUSTSEC-2021-0003 and Cargo.toml in separate commit.
Affected function `SmallVec::insert_many` looks like don't was used directly in rust, but can be somewhere in deps.
There should be some mechanism to not to do this kind of things manually, like dependabot. Actually, dependabot supports rust and can check security articles (at least that noted in description).
Visit more targets when validating attributes
This begins to address #80048, allowing for additional validation of attributes.
There are more refactorings that can be done, though I think they should be tackled in additional PRs:
* ICE when a builtin attribute is encountered that is not checked
* Move some of the attr checking done `ast_validation` into `rustc_passes`
* note that this requires a bit of additional refactoring, especially of extern items which currently parse attributes (and thus are a part of the AST) but do not possess attributes in their HIR representation.
* Rename `Target` to `AttributeTarget`
* Refactor attribute validation completely to go through `Visitor::visit_attribute`.
* This would require at a minimum passing `Target` into this method which might be too big of a refactoring to be worth it.
* It's also likely not possible to do all the validation this way as some validation requires knowing what other attributes a target has.
