As mentioned in https://github.com/boa-dev/boa/pull/2848#issuecomment-1518909512, this uses our new default ICU4X data to replace `char::is_start` and `char::is_continue` from the `boa_unicode` crate with the [`icu_properties`](https://crates.io/crates/icu_properties) crate.
Note that this doesn't deprecate `boa_unicode` yet, since that'll require some discussion about how to proceed with a now unused sub-crate.
This Pull Request implements [Initializers in ForIn Statement Heads](https://tc39.es/ecma262/#sec-initializers-in-forin-statement-heads) from the Annex B. This also cleans up the "annex-b" feature to be able to disable it with `--no-default-features`, since I couldn't test the error messages when the feature is disabled.
This Pull Request fixes some additional Annex B tests.
It changes the following:
- Fixes bugs related to parsing HTML closing comments (`-->`).
- Implements `RegExp::compile` behind the `annex-b` feature.
- Ignores the `legacy-regexp` feature flag, since it's still stage 3.
Small steps towards ES5 conformance.
This PR changes the following:
- Implements HTML comments parsing (`<!--`, `-->`).
- Gates the functionality behind a new `annex-b` feature for `boa_parser`.
- Renames `strict_mode` to `strict` to be consistent with `Parser::set_strict`.

This Pull Request addresses the broken `cargo clippy` lints that is currently causing CI to fail.
This PR migrates our entire test suite to our new testing API.
It changes the following:
- Migrates tests to new test API.
- Cleans up the API to be a bit more descriptive and maintainable.
- Prettifies our test failure display to show the failed scripts.
- Splits our massive `tests.rs` file into smaller sub-suites.
Example output of a failing test:
I'm creating this draft PR, since I wanted to have some early feedback, and because I though I would have time to finish it last week, but I got caught up with other stuff. Feel free to contribute :)
The main thing here is that I have divided `eval()`, `parse()` and similar functions so that they can decide if they are parsing scripts or modules. Let me know your thoughts.
Then, I was checking the import & export parsing, and I noticed we are using `TokenKind::Identifier` for `IdentifierName`, so I changed that name. An `Identifier` is an `IdentifierName` that isn't a `ReservedWord`. This means we should probably also adapt all `IdentifierReference`, `BindingIdentifier` and so on parsing. I already created an `Identifier` parser.
Something interesting there is that `await` is not a valid `Identifier` if the goal symbol is `Module`, as you can see in the [spec](https://tc39.es/ecma262/#prod-LabelIdentifier), but currently we don't have that information in the `InputElement` enumeration, we only have `Div`, `RegExp` and `TemplateTail`. How could we approach this?

Extracted from #2411 to reduce its size a bit.
This PR:
- Renames `Identifier` to `IdentifierName`, which is the name stated in the spec.
- Renames the utility function `check_parser` to `check_script_parser` to prepare for modules.
- Adds some missing `#[inline]` and rewrites some patterns.
This Pull Request changes the following:
- Add early errors for escaped characters in object and class setters and getters.
- Add early errors for escaped characters in class `static`.
- Add early errors for escaped characters in `new.target`.
- Add early errors for legacy octal/decial escapes that are used in string literals before a `"use strict"` directive.
Per the [Standard Library development guide](https://std-dev-guide.rust-lang.org/code-considerations/performance/inline.html):
> You can add `#[inline]`:
>
> - To public, small, non-generic functions.
>
> You shouldn't need `#[inline]`:
> - On methods that have any generics in scope.
> - On methods on traits that don't have a default implementation.
>
> `#[inline]` can always be introduced later, so if you're in doubt they can just be removed.
This PR follows this guideline to reduce the number of `#[inline]` annotations in our code, removing the annotation in:
- Non-public functions
- Generic functions
- Medium and big functions.
Hopefully this shouldn't impact our perf at all, but let's wait to see the benchmark results.

Submitting this as a draft for feedback/second opinions. This draft contains some changes to the documentation.
Quick Overview:
- Potential `Boa` header for Boa's crates added to `boa_engine`.
- Changes the wording to a lot of module headers (See `builtins` module and `object/builtins` module).
- Updating built-in wrapper's code examples to use `?` operator.
- Adds the doc logo URL to a few crates that didn't have it.
The main idea of this draft is to move away from the "This module implements" wording as it feels a bit duplicative when listed under the Modules section (mainly focusing around changes in `boa_engine` to start).
While working on this, I had a question about whether we should be using JavaScript or ECMAScript in the Boa's documentation. We do seem to currently use both, and this draft uses JavaScript heavily in the wording.
This Pull Request restructures the lint deny/warn/allow lists in almost all crates. `boa_engine` will be done in a follow up PR as the changes there are pretty extensive.
