If we know that the peer disconnected while receiving a message in the
generated code, let's shutdown the connection from here instead of
forcing each client to do so.
This commit introduces NamedVariableDeclaration and
SSAVariableDeclaration and allows storing both of them in Variable node.
Also, it adds additional structures in FunctionDefinition and
BasicBlock, which will be used to store SSA form related information.
We assume that variable shadowing is impossible, so then there is no
reason to keep distinct Declaration and Assignment operators after
ReferenceResolvingPass.
We would previously always generate string parameters to pass through
to functions as a `String`. This works fine if the argument is a
`FlyString const&`, but falls apart for optional types where we need to
accept an `Optional<FlyString> const&`.
Support this by implementing a [FlyString] extended attribute which
if present results in the parameter for the function being generated
as a FlyString.
This is how the spec tells us we should be converting to these integer
types.
Also leave around a FIXME to pass through information about the [Clamp]
and [EnforceRange] extended attributes, and port over these instances to
the new WebIDL integer typedefs.
Per:
https://dom.spec.whatwg.org/#concept-reflect
We should be calling `get_attribute_value` for reflected IDL strings.
No functional change as nowhere is performing a reflect on a nullable
type, and just ends up simplifying the code.
In a bunch of cases, this actually ends up simplifying the code as
to_number will handle something such as:
```
Optional<I> opt;
if constexpr (IsSigned<I>)
opt = view.to_int<I>();
else
opt = view.to_uint<I>();
```
For us.
The main goal here however is to have a single generic number conversion
API between all of the String classes.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

$ gn format $(git ls-files '*.gn' '*.gni')
If we don't do this, and there a class in a namespace with the same
name, type resolution gets confused between `<namespace>::<class>` and
`<class>::<constructor>`.
These wrappers will make it much easier to do various operations on the
different ArrayBuffer-related classes in LibWeb compared to the current
solution, which is to just accept a Handle<Object> everywhere (and use
"any" in the *.idl files).

Implemented by adding the extra 3-value syntax as its own case and only
running it when parsing background-position. I'm sure it could be
implemented in a smarter way but this is still a bunch less code than
before. :^)
This means `object-position` will no longer incorrectly accept the
3-value background-position syntax.
Remove the now-ambiguous and unused `position` enum while we're at it.
(This enum only existed as a hack.)
With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.
This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.
I left a few types unconverted to this mechanism because I got tired of
doing this. :^)
Aside from the obvious performance benefits, this will allow us to
properly handle dictionary types. (whose dictionary-ness is only known
at build-time)
Much of the rest of the overload resolution algorithm steps can (and
should) be evaluated at build-time as well, but this is a good first
step.
When wrapping dictionary members, generate_wrap_statement was called
with the pattern "auto {} = ...", where "..." was determined based on
the variable's type. However, in generate_wrap_statement, if a type is
nullable it generates an if statement, so this would end up generating
something along the lines of
if (!retval.member.has_value()) {
auto wrapped_member0_value = JS::js_null();
} else {
auto wrapped_member0_value = JS::Value(...);
}
...which makes the declaration inaccessible. It now generates the same
code, but the "auto" declaration (now an explicit JS::Value declaration)
is outside of the if-statement.
