There is a Stage 1 proposal to standardize this, but it does not seem
to be active.

b0e5609b88 LibJS: Use GetV to look up the toJSON property in SerializeJSONProperty 
The current implementation of step 2a sort of manually implemented GetV
with a ToObject + Get combo. But in the call to Get, the receiver wasn't
the correct object. So when invoking toJSON, the receiver was an Object
type rather than a BigInt.

This also adds spec comments to SerializeJSONProperty.

update all the variables of this type as well.

14d1601a76 LibJS: Remove the VERIFY_NOT_REACHED in link_and_eval_module 
Since the spec does not fully define the entry points of modules what
this means is kind of unclear. But it does work in most cases and can
be useful. We do print out a warning just to clarify why there could be
strange things.

8da6c01d8f LibJS: Remove the JS_TRACK_ZOMBIE_CELLS option 
This feature had bitrotted somewhat and would trigger errors because
PrimitiveStrings were "destroyed" but because of this mode they were not
removed from the string cache. Even fixing that case running test-js
with the options still failed in more places.

a962ee020a LibJS+LibRegex: Don't repeat regex match in regexp_exec() 
LibRegex already implements this loop in a more performant way, so all
LibJS has to do here is to return things in the right shape, and not
loop over the input string.
Previously this was a quadratic operation on string length, which lead
to crazy execution times on failing regexps - now it's nice and fast :^)

Note that a Regex test has to be updated to remove the stateful flag as
it repeats matching on multiple strings.

2b028f6faa LibRegex+LibJS: Avoid searching for more than one match in JS RegExps 
All of JS's regular expression APIs only want a single match, so avoid
trying to produce more (which will be discarded anyway).

stored time value to local time.

281b0411f2 LibJS: Implement conversion of strings to BigInts according to the spec 
The spec defines a StringToBigInt AO which allows for converting binary,
octal, decimal, and hexadecimal strings to a BigInt. Our conversion was
only allowing for decimal strings.

8bdf6441b1 LibJS: Use u32 for the JS::Shape property count 
We don't need to support more than 2^32 object properties anyway, so
there's no point in using 64-bit property counts.

This small reduction in memory usage makes test-js run ~10% faster on
x86_64 locally.

7a742b17da LibJS: Store ECMAScriptFunctionObject bytecode in an OwnPtr 
Using an Optional was extremely wasteful for function objects that don't
even have a bytecode executable.

This allows ECMAScriptFunctionObject to fit in a smaller size class.

4a51165f5f LibJS: Reorganize JS::Shape members a little bit 
Now that AK::Weakable doesn't have a bunch of padding at the end,
let's move the smaller members of JS::Shape to the end, since there's
nothing to fold into at the start.

1469057033 LibJS: Make JS::Shape smaller by using OwnPtr<HashMap> for transitions 
Many shapes don't have any forward transitions to cache, so we can save
a bunch of memory (and time) by only creating the cache maps when
actually needed.

30fcb07fe8 LibJS: Make JS::Environment smaller by reordering members
