1850652881 LibJS/Bytecode: Check if eval function is a function 
When overriding 'eval' to a non-function value, the interpreter would
crash. Now it handles this case swiftly, throwing a TypeError.

a2f60911fe AK: Rename GenericTraits to DefaultTraits

b1b2ca1485 LibJS: Add basic monomorphic caching for PutById property access 
This patch makes it possible for JS::Object::internal_set() to populate
a CacheablePropertyMetadata, and uses this to implement a basic
monomorphic cache for the most common form of property write access.

bb9230bbcd LibJS: Remove redundant Store op 
If the property for GetByValue in Generator::load_from_reference
is a calculated value this would be stored in an allocated
register and returned from the function. Not all callers want
this information however, so now only give it out when asked for.

Reduced the instruction count for Kraken/ai-astar.js function
"neighbours" from 214 to 192.

8eb9c2dc54 LibJS/JIT: Add fast path for number comparisons 
So far only less_than was using a fast path. This commits uses the same
path for less_than_equals, greater_than and greater_than_equals.

c170dd323e LibJS: Make eval() prevent GetGlobal usage less aggressively 
Before usage of GetGlobal was prevented whenever eval() is present in
the scope chain.

With this change GetGlobal is emitted for `g` in the following program:
```js
function screw_everything_up() {
    eval("");
}

var g;
g;
```

It makes Octane/mandreel.js benchmark run 2x faster :)

21b946791e LibJS: Link with libatomic on i*86 
Basically, this would be needed on any platform where the compiler
cannot tell at compile time whether or not some atomic size is
lock-free.

9c6c2284d9 LibJS: Fix build error when some atomics are not lock-free 
Normally, we want to avoid accidentally using such atomics, since
they're much slower. In this case however, we're just implementing
another atomics API, it is then up to the JavaScript code to avoid
using the slow atomics.

bf3fce1766 LibJS: Add Date.parse formats for the output of Date.prototype.to*String 
We currently cannot parse the output of `toString` and `toUTCString`.
While the spec does not require such support, test262 expects it, and
all major engines support it.

1d8ec677a3 LibJS/JIT: Add fast path for cached GetVariable accesses

as long as they are cached and initialized.

20% speed-up on Octane/zlib.js :^)

38dd284915 LibLocale: Update to CLDR version 44.0.1 
https://cldr.unicode.org/index/downloads/cldr-44

Notable changes that affect us include:

* The Islamic Calendar is now localized as the Hijri Calender (in en-US)
  but has not been updated for all locales. So this patch updates tests
  where possible and removes a few test cases that currently cannot be
  localized.

* The und locale has received more likely subtag data (the und locale is
  basically a pseudo-locale meaning "undetermined").

* The exponential symbol in the Arabic number system was changed from
  U+0627 to U+0623.

f03d4a1ffe LibJS/JIT: Resolve the PropertyLookupCache pointers at JIT time

let's put the pointer directly into the instruction stream.

7e3cfaf08c LibJS/JIT: Include headers before they are used 
JIT_ARCH_SUPPORTED is defined in LibJIT/Assembler.h, so we need to
include it first.

This change also moves the non-JIT headers outside the #ifdef

bacbd830fe LibJIT: Make X86_64Assembler::native_call take u64 instead of void* 
Now that x86-specific Assembler will be compiled on every architecture
we can't rely on void* being the right width.
It also fixes compilation on targets which have void*
be different length from u64 (WASM in particular).

8aa35f4fab LibJIT+LibJS: Rename Assembler to X86_64Assembler 
This is in preparation for making LibJIT support multiple architectures.
Assembler will now be typedefed to the specific assembler
for a particular architecture.
Additionally, there's now JIT_ARCH_SUPPORTED which is defined on
architectures which LibJIT supports.
