Always allow rustdoc-json tests to contain long lines
The rustdoc-json test syntax often requires very long lines, so the checks for long lines aren't really useful.
`@aDotInTheVoid` told me she'd like this and

you're gonna tell me that the implementation is terrible. at least the performance seems reasonable: 2.5s after and 2.5s before.
Fix pretty printing of unsafe binders
We used to render `unsafe<> i32` as `i32`, and `unsafe<'a> &'a i32` as `for<'a> &'a i32`.

Review with whitespace b/c adding a new argument changes some the wrapping of some function calls.
When encountering a resolve E0575 error for an associated method (when a type was expected), see if it could have been an intended return type notation bound.
```
error[E0575]: expected associated type, found associated function `Trait::method`
--> $DIR/bad-inputs-and-output.rs:31:36
|
LL | fn foo_qualified<T: Trait>() where <T as Trait>::method(i32): Send {}
| ^^^^^^^^^^^^^^^^^^^^^^^^^ not a associated type
|
help: you might have meant to use the return type notation syntax
|
LL - fn foo_qualified<T: Trait>() where <T as Trait>::method(i32): Send {}
LL + fn foo_qualified<T: Trait>() where T::method(..): Send {}

```
ensure we always print all --print options in help
Closes#137853
Refactors the PRINT_KINDS map into a public const so we always print every option for print. the list is quite long now, and idk if long term we want to keep printing all these options from --help.
Remove `:` from `stack-protector-heuristics-effect.rs` Filecheck Pattern
With function sections, the assembly label does not necessarily end in `:`.
Remove trailing `:` to be more consistent with the rest of the existing Filecheck patterns.
```
// CHECK-LABEL: local_string_addr_taken
#[no_mangle]
pub fn local_string_addr_taken(f: fn(&String)) {
let x = String::new();
f(&x);
```
Implement `#[cfg]` in `where` clauses
This PR implements #115590, which supports `#[cfg]` attributes in `where` clauses.
The biggest change is, that it adds `AttrsVec` and `NodeId` to the `ast::WherePredicate` and `HirId` to the `hir::WherePredicate`.
test(codegen): add looping_over_ne_bytes test for #133528
Adds test for #133528.
I renamed the function to `looping_over_ne_bytes` to better reflect that it is doing.
I also set the min llvm version to 20 as this was presumably a llvm bug that was fixed in version 20.
I didn't tie the test to any specific architecture, as we are testing llvm output.
tests: Unignore target modifier tests on all platforms
These tests can be `check-pass` and do not need dynamic libraries.
Also remove other unnecessary stuff from them.

Add rustdoc support for `--emit=dep-info[=path]`
Fixes#91982.
This PR adds the `--emit=dep-info` command line flag support. It will be helpful for `cargo` development.

rustdoc: when merging target features, keep the highest stability
This addresses https://github.com/rust-lang/rust/issues/137366. (Not closing since we might consider a backport.)
rustdoc wants to pretend that it runs for all targets at once and has all target features, so `tcx.rust_target_features()` will actually be all the target features. For target features that exist on multiple targets, the stability info for one of the targets will be picked (first or last in the list, I guess). All the code consuming that query has to be aware that the data is basically nonsense when running in rustdoc, but the logic checking for unstable or forbidden `#[target_feature]` attributes was not aware of that.
This PR makes the `tcx.rust_target_features()` info in rustdoc slightly less nonsensical (and decidedly less random) by having the "most stable" target feature take precedent. That deals with #137366 (a conflict between a stable and a "forbidden" target feature of the same name for different targets), and also deals with the situation (that we did not seem to have yet) of a conflict between a stable and an unstable target feature of the same name. Note that if there are two unstable target features of the same name, rustdoc might still require the "wrong" nightly feature to be enabled -- but this can only possibly affect unstable code so I guess we can wait until that actually happens, and then someone will have to rewrite this entire thing to be less hacky.
improve `simd_select` error message when used with invalid mask type
followup to https://github.com/rust-lang/rust/pull/137828
This PR improves the error message for an invalid `simd_select` mask type, and adds testing for `simd_scatter` and `simd_gather` being used with invalid mask types.
the `simd_masked_load` and `simd_masked_store` intrinsics already generated a better error message:
