This includes adding a padding slot to the stack handler, which is done for all

52ff3ae48b [builtins] implement RunMicrotasks pump as a code stub
- Implement RunMicrotasks in CSA to prevent a potentially large number
  of jumps between C++ and JS code while consuming te queue. Appears to
  provide a ~60% speedup in microtask-heavy code, which from limited
  testing appears to scale linearly.

  The code-stub microtask pump bails out to the old C++ microtask pump
  if it encounters a CallHandlerInfo microtask, and remains in C++ for
  the remainder of the queue (returning to the JS/stub implementation
  after the bailed out queue is exhausted).

- Add a variation of JSEntryStub which enters the new RunMicrotasks code
  stub.

- Add a new RunMicrotasks helper to Execution, which uses the
  RunMicrotasks entry stub.

822be9b238 Normalize casing of hexadecimal digits
This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.

Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.

Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters

Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

2a50797d40 [runtime] Reset the current context when leaving the runtime in the CEntryStub
This CL introduces a Context::kInvalidContext sentinel value to make clear that
no context is active. We silently accept smi 0 (= nullptr) as a non-set context
which usually was the default value making it hard to ensure whether this
happened on purpose or not.

eeb3222441 Allow move semantics on Labels
The Label class currently allows to be copied on all platforms except
for arm64, where it can not be copied or moved.
This allows too much though:
Copying a label even on another platform than arm64 might fail if the
label was linked already, because only one of the copies will be bound
later, and the other will fire a DCHECK error in its destructor.

This CL changes the restriction to never allow to copy construct or
assign a Label, but allow move construction and move assignment on all
platforms except arm64.
This will allow to place Labels in containers, as will be done in
Liftoff (except for arm64, where it still needs to be allocated on the
heap).

a087abb062 [cleanup] Don't pass resume_mode to ResumeGenerator.
There's not really a point in passing the resume_mode as parameter to
the ResumeGenerator builtin. Instead we could as well just store the
mode to the generator object directly.

Drive-by-fix: On Intel allocate the generator to the new.target register
immediately so we don't need to move it there later.

c192569047 Precalculate the exception handler address.
We expect no GC between the call to UnwindAndFindHandler and
the call to that handler. We can precalculate the handler entrypoint
and then let the CEntryStub just load and call that address.

The main motivation for this change is the wasm on the native heap
work, and making the CEntryStub able to work with non- Code* values.

fd306a0658 Allow constexpr RegList construction from Registers
Before, the standard way to create a RegList was either:
RegList list = (1 << 0) | (1 << 1) | ...
or
RegList list = rax.bit() | rdx.bit() | ...

The first way allows to make the RegList constexpr, but needs comments
to document which registers you are referring to, and it has no checks
that all bits you set on the RegList actually belong to valid registers.
The second one uses the symbolic names, hence is much more readable and
makes it harder to construct invalid RegLists. It's not constexpr
though, since the {bit()} method on the register types is not constexpr.

This CL adds a constexpr accessor to get the code and bit of a
constexpr Register, and adds a helper method to create a constexpr
RegList like this:
constexpr RegList list = Register::ListOf<rax, rdx, rdi>();

This new method is used in a number of places to test its
applicability. Other uses of the old pattern remain and can be cleaned
up later.

14917b6531 [heap] Implemented write protected code pages.
This CL provides the basic infrastructure on the GC side for write protected code pages.

The only thing missing on the GC side is the out-of-line free list implementation. In this
CL sweeper threads and the mutator need to synchronize when page protection mode changes.
This would not be necessary if the sweepr use and out-of-line free list.

Code allocation is currently protected by a CodeSpaceMemoryModificationScope. This may
go away with a unification of code space allocation and initialization that will happen
later.

One thing missing in this CL: freshly added pages are still read+write+executable. This
also needs to change: WIP

9f4f3c28ec Simplify DoubleToI stub.
The DoubleToI stub is no longer called outside of TurboFan, and always in the
same way:

  - The parameter is on top of the stack.
  - The stub is always called in a slow path.
  - It truncates.

Therefore, we can simplify it to only support this case and remove dead
code.

On top of this, since the stub is always considered to be on a slow path for all
backends, this patch takes the opportunity to remove the `skip_fastpath`
optimisation. This would generate a stub which does not handle all inputs,
assuming that the backend already handled some of the inputs in a fast
path. Removing this allows the stub to have the same behaviour on all targets.

On Arm, this patch reworks the stub a little. We could use ip instead of saving
and restoring a register on the stack. Also, comments would mention that we
assume the exponent to be greater than 31 when the it can be 30 or higher. As
done for Arm64, let's check this at runtime in debug mode.

On Arm64, we can also implement the stub without pushing and poping off the
stack. It needs 2 general purpose and a double scratch registers which we have
reserved already (ip0, ip1 and d30). This removes the need to check that the
stack pointer is always 16-bytes aligned.

Finally, this also fixes a potential bug on Arm64, in the
`GetAllocatableRegisterThatIsNotOneOf` method which is now removed. We were
picking an allocatable double register when we meant to pick a general one.
