b5875700e2 LibJS: Don't hang when parsing invalid destructuring assignment target 
Previously, certain crafted input could cause the JS parser to hang, as
it repeatedly tried to parse an EOF token after hitting an "invalid
destructuring assignment target" error. This change ensures that we
stop parsing after hitting this error condition.

9c63f9854b LibJS/JIT: Remove incorrect check for empty tag 
This check is not required and prevented put_by_value
to take the actual fastpath.

7% speed-up on Kraken/ai-astar.js, covers up most of the regression
from adding more fast paths. :^)

b532dedc91 LibJS/JIT: Add fast path for GetById of Array.length 
Array.length is magical (since it has to reflect the number of elements
in the object's property storage).

We now handle it specially in jitted code, giving us a massive speed-up
on Kraken/ai-astar.js (and probably many other things as well) :^)

e41f0d9dec LibJS/JIT: Add fast path for loose equality check between 2 objects 
There are more fast paths to be added here, just starting with this
one since it's heavy on Kraken/ai-astar.js :^)

cfdb8a2756 LibJS/JIT: Update "unwind context" stack in JIT code 
Until now, the unwind context stack has not been maintained by jitted
code, which meant we were unable to support the `with` statement.
This is a first step towards supporting that by making jitted code
call out to C++ to update the unwind context stack when entering/leaving
unwind contexts.

We also introduce a new "Catch" bytecode instruction that moves the
current exception into the accumulator. It's always emitted at the start
of a "catch" block.

crash. Now it handles this case swiftly, throwing a TypeError.

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

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

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.
