This Pull Request is part of #279.
It adds a string interner to Boa, which allows many types to not contain heap-allocated strings, and just contain a `NonZeroUsize` instead. This can move types to the stack (hopefully I'll be able to move `Token`, for example, maybe some `Node` types too.
Note that the internet is for now only available in the lexer. Next steps (in this PR or future ones) would include also using interning in the parser, and finally in execution. The idea is that strings should be represented with a `Sym` until they are displayed.
Talking about display. I have changed the `ParseError` type in order to not contain anything that could contain a `Sym` (basically tokens), which might be a bit faster, but what is important is that we don't depend on the interner when displaying errors.
The issue I have now is in order to display tokens. This requires the interner if we want to know identifiers, for example. The issue here is that Rust doesn't allow using a `fmt::Formatter` (only in nightly), which is making my head hurt. Maybe someone of you can find a better way of doing this.
Then, about `cursor.expect()`, this is the only place where we don't have the expected token type as a static string, so it's failing to compile. We have the option of changing the type definition of `ParseError` to contain an owned string, but maybe we can avoid this by having a `&'static str` come from a `TokenKind` with the default values, such as "identifier" for an identifier. I wanted for you to think about it and maybe we can just add that and avoid allocations there.
Oh, and this depends on the VM-only branch, so that has to be merged before :)
Another thing to check: should the interner be in its own module?
This Pull Request fixes some warnings and clips errors. It conflicts with the VM/non-VM PR, so should probably go in first, so that this branch gets properly updated and we get the list of real warnings/errors there.
This PR fixes some vm implementation code. All our internal tests should now pass with the vm enabled.
There are only a few (~100) 262 tests left that currently break with the vm, that previously worked.
Previously when we had the `context.throw_` methods (like `context.thtrow_type_error()`) they were limited as to where we could call them, e.i. a function that returned `JsResult<JsValue>`. So we had to call the `context.construct_` methods with an explicit `Err()` enum wrap to throw in functions that returned non-jsvalues (which happens a lot).
Now, with this PR the throw methods have a generic `JsResult<R>` return that can return in any `JsResult<T>` returning function. Which cleans the API and makes the user experience a bit better.
```rust
return Err(context.construct_type_error("..."));
// to
return context.throw_type_error("...");
```

Hi, first time contributor :)
I was playing with getting the test262 test runner working and found a couple small things that I thought would've made my life a bit easier. I've split them into separate commits. Just let me know if you disagree with any and we can drop that commit. And of course, let me know of any changes you'd like to see :)
The changes are:
- Adds details to the documentation on the `--suite` command to `boa_tester`. I was trying to pass a path starting with `./test262/` for a bit before I looked at the code and saw what it was doing.
- Changes the individual test output when verbosity is > 1. Because the tests are run in parallel, the "Result" line for a given test was frequently not immediately after the "Started" line. This made it hard to determine which test had failed. The new output includes the test name in the result line, and also changes the format of all the individual-test-output lines to begin with the test name.
- Adds a `--disable-parallelism` flag. Even with the adjustments to the test output, it was still a bit hard to follow. Running serially for small sub-suites produces output that can be more easily scanned IMO. I added this as a "disable" flag (as opposed to "enable parallelism") in order to maintain the current default of running in parallel.

This PR adds conformance results for the VM branch both for PRs and for the conformance results in GitHub pages (even if these are not currently being shown). I'm not 100% sure how this will really work, as I'm not very used to the syntax to concatenate strings.

* Handle non-strict functions in strict functions
* Enable strict mode for functions defined in a strict context
* Don't consider panic fixes as "new failures"
* Improved coding style
* Fixed Test262 tester for the testing update
* Ignore JSON module tests
* Test262 uses _FIXTURE at any point of the file name
* Added some result changes for Test262 result comparisons
* Added a bug and a panic to test the changes in the comparator
* Remove explicit todo!()
* Fixing output for test links
* Force comment
* Reducing failures so that commenting works
* New test
* Fixed a bit of formatting
* Reverted purposedly introduced bugs
* Added a "details" section for the test262 test diff
* Fix bold
When the test262 conformance comments are added to a PR, it will now
show the percentage symbol for the conformance, to show up it's
actually a conformance percentage.
* Improved CI workflows
This improves several things in the CI workflows:
- More conformant Test262 result generation
- Benchmarks should now show comments for all users
- Added Test262 result comparison comments to Pull Requests
* Fixed typo
* Checking the comment generation
* Fixing conditions to test comments
* Fix a couple of bugs on the comparator
* Fixed format
* Trying to fix comment updating
* Removing commit autor when searching
* Replace the comment instead of appending
* Switched back to the `pull_request_target` event
