6061da3382 LibJS: Overload Instruction::length() on variable-length instructions 
This allows the DISPATCH_NEXT() macro to do the math to find the next
instruction boundary point without performing a function call.

a2b7e04da3 LibJS: Defer looking up the realm in ordinary_call_evaluate_body() 
We don't actually need the realm for normal function calls, so we
can avoid looking it up on the EC stack in that case.

35275651e3 LibJS: Skip stack overflow check in ESFO::prepare_for_ordinary_call() 
We already do a stack overflow check when entering run_bytecode(),
which is the first thing that happens when we actually invoke the ESFO
executable.

95ba74d934 LibJS: Remove redundant VERIFY in run_executable() 
Getting the running_execution_context() already verifies that the
execution context stack is non-empty, we don't need to do it separately
here as well.

6de1a0aeaf LibJS: Don't cache a pointer to accumulator register in run_bytecode() 
The old accumulator register is really only used to pass the end
completion to the caller of run_bytecode() nowadays. As such, we don't
need to cache a pointer to it for fast access. One less thing to do
on run_bytecode() entry.

4d17707b26 LibJS: Store bytecode VM program counter in ExecutionContext 
This way it's always automatically correct, and we don't have to
manually flush it in push_execution_context().

~7% speedup on the MicroBench/call* tests :^)

behaves in the same way as the `transition-property` longhand.4

233097c250 LibJS: Inline part of VM::run_queued_promise_jobs() 
Most of the time there are no queued promise jobs to run after exiting
a stack frame. By moving the check inline, leaving a function call gets
a measurable speedup in the common case.

b4554c01db LibJS: Mark ESFO path for [[Call]] on a class constructor [[unlikely]] 
This is an exception path that's not supposed to be called normally,
so let's mark it unlikely.

6ec4d0f5ba LibJS: Mark stack overflow exception code path as [[unlikely]]

[[unlikely]] annotation.

580b892b9e AK: Demote VERIFY in NonnullRefPtr to ASSERT 
NonnullRefPtr almost always has a non-null pointer internally, that's
what the class is for, after all! The one edge case where it has null
internally is after you move() it. But it's always a bug to use an
NNRP after moving from it, and we have clang-tidy yelling at us if
that ever happens.

Demoting this removes a gazillion overly paranoid null checks.

074ca5d5b4 LibJS: Make ESFO::ordinary_call_evaluate_body() return TCO<Value> 
This matches what the caller wants to return and allows us to simplify
a bunch of logic around returning a value or throwing.

8a3c66d8a6 LibWeb: Make a bunch of CSP classes not realm associated 
These are not associated with a javascript realm, so to avoid
confusion about which realm these need to be created in, make
all of these objects a GC::Cell, and deal with the fallout.

74c803c87b LibWeb: Ensure |= value selector handles multiple segments correctly 
Previously, the `|=` would not compare strings containing `-`
characters correctly because it would only compare the element
attribute up to the first `-` character.

5f1a30197c LibCrypto: Remove the concept of invalid big integers 
This concept is rarely used in codebase and very much error-prone
if you forget to check it.

Instead, make it so that operations that would produce invalid integers
return an error instead.

a05be67e4a LibJS: Let invokers (callers) of [[Call]] allocate ExecutionContext 
Instead of letting every [[Call]] implementation allocate an
ExecutionContext, we now make that a responsibility of the caller.

The main point of this exercise is to allow the Call instruction
to write function arguments directly into the callee ExecutionContext
instead of copying them later.

This makes function calls significantly faster:
- 10-20% faster on micro-benchmarks (depending on argument count)
- 4% speedup on Kraken
- 2% speedup on Octane
- 5% speedup on JetStream
