`Module::functions` created clones of all of the functions in the
module. It provided a _slightly_ better API, but ended up costing around
40ms when instantiating spidermonkey.
Instead of multiple loops and multiple vectors, parse Wasm expressions
in a simple loop. This gets us from ~450ms to instantiate spidermonkey
to ~280ms.
This works for now, but is technically still not spec compliant. Right
now, we're (potentially) missing one bit when reading function indices.
See the relevant issue: #24462.
The WebAssembly spec never relies on host system information, like
size_t. For consistency's sake, we should stick to the usage of u32's
instead of size_t's. This didn't cause issues before because
LEB128-encoded u64's are a superset of LEB128-encoded u32's.
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).
This commit is auto-generated:

Similar to POSIX read, the basic read and write functions of AK::Stream
do not have a lower limit of how much data they read or write (apart
from "none at all").
Rename the functions to "read some [data]" and "write some [data]" (with
"data" being omitted, since everything here is reading and writing data)
to make them sufficiently distinct from the functions that ensure to
use the entire buffer (which should be the go-to function for most
usages).
No functional changes, just a lot of new FIXMEs.
`Stream` will be qualified as `AK::Stream` until we remove the
`Core::Stream` namespace. `IODevice` now reuses the `SeekMode` that is
defined by `SeekableStream`, since defining its own would require us to
qualify it with `AK::SeekMode` everywhere.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Same as Vector, ByteBuffer now also signals allocation failure by
returning an ENOMEM Error instead of a bool, allowing us to use the
TRY() and MUST() patterns.
It's possible for the module to request too many locals, we now reject
such modules instead of trying to allocate space for them.
The value itself is chosen arbitrarily, so future tweaks _might_ be
necessary.
