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.

f03d4a1ffe LibJS/JIT: Resolve the PropertyLookupCache pointers at JIT time 
We know where the lookup cache is by the time we're jitting code, so
let's put the pointer directly into the instruction stream.

c92954db36 LibJS/JIT: Resolve the GetById property name at JIT time 
We can resolve the IdentifierTableIndex to a DeprecatedFlyString& once
when jitting the code, instead of every time GetById executes.

e400682fb1 LibJS/JIT: Support alternative entry point blocks 
If Interpreter::run_and_return_frame is called with a specific entry
point we now map that to a native instruction address, which the JIT
code jumps to after the function prologue.

38f3b78a1d LibJS: Store the bytecode accumulator in a dedicated physical register 
We now use a dedicated physical register to store the bytecode
accumulator, instead of loading and storing it to the memory everytime.

68f4d21de2 LibJS: Lazily collect stack trace information 
The previous implementation was calling `backtrace()` for every
function call, which is quite slow.

Instead, this implementation provides VM::stack_trace() which unwinds
the native stack, maps it through NativeExecutable::get_source_range
and combines it with source ranges from interpreted call frames.

fb7b4b9c59 LibJS/JIT: Provide source location information for JIT code 
This works by walking a backtrace until the currently executing
native executable is found, and then mapping the native address
to its bytecode instruction.

1341f4438d LibJS: Save scheduled jumps when entering unwind contexts 
These are then restored upon `ContinuePendingUnwind`.
This stops us from forgetting where we needed to jump when we do extra
try-catches in finally blocks.

instead of having them in Interpreter.cpp.

6a3f27509f LibJS: Avoid IdentifierTable lookup in cached GetGlobal op 
When we hit the cache in GetGlobal, we don't need the identifier string
at all, so let's defer fetching it until after the cache miss.

7% speed-up on Kraken/imaging-gaussian-blur.js :^)
