1d8a601f96 LibJS/JIT: Add builtin for Math.log() 
Note that we still call out to a C++ helper, but by having a builtin,
we still avoid the cost of a full JS function call.

f19349e1b6 LibJS: Instantiate primitive array expressions using a single operation 
This will not meaningfully affect short array literals, but it does
give us a bit of extra perf when evaluating huge array expressions like
in Kraken/imaging-darkroom.js

86b85aa68b LibJS: Introduce Builtins 
Builtins are functions that can be detected during bytecode generation
and enable fast-paths in the JIT.

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

e8c0cea5f9 LibJS/JIT: Use right shift to extract type tags in equality codegen 
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.

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.

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.

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