0a09eaf3a1 LibJS+LibTest: Use JS::Script and JS::SourceTextModule in test-js 
Instead of creating a Parser and Lexer manually in test-js, we now
use either JS::Script::parse() or JS::SourceTextModule::parse()
to load tests.

10c489713d LibJS+LibWeb: Let JS::Script::parse() return a list of errors (on error) 
These are really supposed to be a list of SyntaxError objects, but for
now we simply return all the Parser::Error objects we got from Parser.

5fa02b8a9e LibJS: Add a barebones SourceTextModule class 
This corresponds to "Source Text Module Record" from the spec.

f08a46bd9e LibJS: Make JS::Script keep the VM alive 
Script has a Handle member (m_realm), and for handles to remain valid,
the VM must stay alive.

df5414f47f LibJS: Reorganize ExecutionContext a little bit 
- Move it to a separate header file
- Annotate the members that represent spec slots
- Reorganize the members (by spec vs non-spec)

4f7e14e0aa LibJS: Reorder the global eval function call detection conditions a bit 
This just makes it clearer, since the actual check is off-screen, making
the reader wonder what that check is for.

f7a68ae998 LibJS: Mark two JS::Reference functions const 
These two are inherently const, and the next commit needs to call them
on a const object, so let's just mark them const.

bf0315ff8f LibRegex: Avoid excessive Vector copy when compiling regexps 
Previously we would've copied the bytecode instead of moving the chunks
around, use the fancy new DisjointChunks<T> abstraction to make that
happen automagically.
This decreases vector copies and uses of memmove() by nearly 10x :^)

910de95e7a LibJS: Add a fast failure path to try_parse_arrow_function_expression() 
The save/load of parser state performed by lookahead parsing is quite
expensive so let's try to avoid it in the most common case.

This is a 15-20% speedup on various chunks of JS I've tested. :^)

a50e33abe3 LibJS: Skip ID_{Start,Continue} property lookup for any ASCII characters 
Before this change, Lexer::is_identifier_{start,middle}() would do a
Unicode property lookup via Unicode::code_point_has_property() quite
frequently, especially for common characters like .,;{}[]() etc.

Since these and any other ASCII characters not covered by the alpha /
alphanumeric check are known to not have the ID_Start / ID_Continue
(except '_', which is special-cased now) properties, we can easily
avoid this function call.

f62477c093 LibWeb: Implement HTML fragment serialisation and use it in innerHTML 
The previous implementation was about a half implementation and was
tied to Element::innerHTML. This separates it and puts it into
HTMLDocumentParser, as this is in the parsing section of the spec.

This provides a near finished HTML fragment serialisation algorithm,
bar namespaces in attributes and the `is` value.

d6cfa34667 AK: Make URL::m_port an Optional<u16>, Expose raw port getter 
Our current way of signalling a missing port with m_port == 0 was
lacking, as 0 is a valid port number in URLs.

af5b62d8cd LibWeb: Move url_{encode, decode} to URL/URLSearchParams.{h, cpp} 
The new URL built-in that will reside in URL.{h, cpp} will have an
URLSearchParams member, which means it has to include its header, and
as such URLSearchParams.h can't include URL's header, which it needs as
it uses the url_{encode, decode} functions.

35cc579264 LibJS: Also set ExecutionContext::realm in Bytecode::Interpreter::run() 
I forgot to consider the bytecode Interpreter when adding a Realm to the
ExecutionContext. This should make it a lot less crashy again :^)

1d47ec380f LibWeb: FlexBox: Use correct source when querying for the main size 
This was an error in understanding what calculated_values are and that
those are not what is wanted when getting the main available size of the
box in the FlexFormattingContext.
The calculation around the size calculation is still a bit wonky, but
this is definietly better.

5b19e9239a LibC: Upgrade memmove() to memcpy() when possible 
We were missing out on opportunities to use memcpy() instead of
memmove() when the source and destination don't overlap.
