This CL removes a CHECK_LE that does not hold in all cases. After
moving all elements to the front, current_pos will point to the next
free spot. In the case where an object is 'packed', i.e. each index
has a non-undefined value, and the length is smaller then the max
index, current_pos will be greater than the length (limit in the code).
Sidenote: The block after taking the minimum (where the counted
undefineds get set) will not be affected. In the case where
num_undefined > 0, current_pos should be guaranteed to be smaller
than limit, as long there are no accessors with side-effects.

At the moment, the whole WebAssembly compilation may run in a single
background task. On a low-end device, this can mean that the background
thread is busy for seconds and thereby blocks other tasks, see e.g.
https://crbug.com/914757.
With this CL we re-schedule compilation tasks after every 50ms. These
50ms are an arbitrary number. I don't want to introduce too much
overhead, but since this is in the background we also don't have to
make tasks super short.
Tasks which are going to compile with TurboFan will be posted with
lower priority.
This change requires changes in the CancelableTaskManager. At the
moment it is not possible that a background task posts a new task
which is managed by the same task manager as itself. The problem is
about how to deal with another thread which calls CancelAndWait
concurrently. At the moment, if a new task gets posted after the call
to CancelAndWait, then `CHECK(!canceled_)` in
CancelableTaskManager::Register will fail. If we used a lock to
synchronize the calls to CancelAndWait and Register, then there would
be a deadlock, where the thread which calls CancelAndWait waits for
the task which wants to call Register, but at the same time blocks that
task by holding the lock.
With the change here, posting a task after the call to CancelAndWait
will just immediately cancel the new task. This matches the behavior
you would get if CancelAndWait is called right after calling Register.

In most cases, the language mode can be inferred from the closure and
the context. Computing the language mode instead of passing it around
simplifies the ICs and will make it possible to go towards lazily

the feedback vectors and with lazy feedback allocation we may not always
have feedback vectors. Since computing language mode is a bit expensive
we want to defer it as far as possible.
In Array builtins and other builtins like Reflect.Set we need to force a

SetProperty methods allow the language mode to be overridden when needed.
This is a first cl in a series of cls, that will defer the language mode
computation further and remove language mode where it is not needed.

of arguments (which is one more now, temporarily), just forward all
arguments down via MacroAssembler and TurboAssembler to

Interestingly, this requires more specific types sometimes (int instead

not recognize any more that the value is a constant, and emits a
warning about a possibly truncating implicit conversion.

This CL fixes two bugs. First, when looking for a free spot while
moving elements to the front, the prototype chain was also considered,
even though an object at a specific index might have a hole (free
spot).
Second, when moving an element to the front, we are not allowed to
delete it immediately (to preserve semantics when interacting with
non-extensible objects). Such an element is then a free spot, but
won't be recognised as such. This CL sets that element to undefined
after it was moved, to mark it as a free spot.

This is a reland of fd49c8bb43
Original change's description:
> [heap] Optimize MemoryChunk::FromAnyPointerAddress
>
> Currently this function requires the caller to hold a mutex for the
> large page chunk hashtable and performs a hashtable lookup.
>
> This patch adds a header sentinel field in each MemoryChunk. The field
> is then used to distinguish large object slots from ordinary slots.

This CL adds handling for almost all calls, and for some load and store
bytecodes in the serializer and marks the relevant call targets as
"serialized for compilation".

The previous implementation of MicrotaskQueue::RunMicrotasks() didn't
support non-default MicrotaskQueue as RunMicrotasks builtin couldn't
take a parameter.
This CL updates the entry trampoline for RunMicrotasks builtin to pass
a MicrotaskQueue parameter to support non-default one.

The function body decoder already tracks reachability and only calls
the backend for reachable code. Thus the checks in the TF backend can
be skipped.
Note that there was already a DCHECK in place that checks whether
{SsaEnv::reached()} always returns true. This was to give fuzzers a
chance to prove the reachability analysis in the function body decoder
wrong. Since this did not happen, we can not remove the {reached()}
method from SsaEnv, since it always returned true anyway.
