62fa048749 [wasm] Reschedule compilation tasks
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.

3ed8675b9c PPC/s390: [test] Refactor AllocateAssemblerBuffer
Port 1a1f4e1ef4

Original Commit Message:

    Refactor the AllocateAssemblerBuffer helper for the new Assembler API.
    This is the only non-mechanical part, all other callsites that create
    Assembler instances can be trivially changed to the new API. This will
    be done in a separate CL.

0896599f6f Change SetProperty/SetSuperProperty to infer language mode when possible
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
allocating feedback vectors. Currently ICs obtain the language mode from
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
language mode when setting the properties. To support these cases the
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.

30617b7748 PPC/s390: Use forwarding constructors for MacroAssembler
Port edab9a2021

Original Commit Message:

    and TurboAssembler. Instead of listing all the different combinations
    of arguments (which is one more now, temporarily), just forward all
    arguments down via MacroAssembler and TurboAssembler to
    TurboAssemblerBase.
    Interestingly, this requires more specific types sometimes (int instead
    of size_t), since further down the forwarding chain, the compiler does
    not recognize any more that the value is a constant, and emits a
    warning about a possibly truncating implicit conversion.

4bf28a33ee [array] Fix prototype chain interaction in sort pre-processing
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.

fab59bbb08 Support non-default MicrotaskQueue on RunMicrotasks builtin
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.

314da8eed2 [wasm] Remove reachability checks from TF backend
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.

edab9a2021 Use forwarding constructors for MacroAssembler
and TurboAssembler. Instead of listing all the different combinations
of arguments (which is one more now, temporarily), just forward all
arguments down via MacroAssembler and TurboAssembler to
TurboAssemblerBase.
Interestingly, this requires more specific types sometimes (int instead
of size_t), since further down the forwarding chain, the compiler does
not recognize any more that the value is a constant, and emits a
warning about a possibly truncating implicit conversion.

943b5d029d PPC/s390: [assembler] Allow to pass custom buffer implementations
Port 1a3aab51f6

Original Commit Message:

    When generating an Assembler, you currently have two choices: Either
    let the Assembler allocate a growable internal buffer, which is owned
    by the Assembler. Or provide an externally allocated buffer, which
    cannot grow.
    This CL changes this interface to allow providing any implementation of
    a buffer. The provided buffer can be a view to an externally owned
    buffer, which still can grow.
    This will be used to split WebAssembly compilation and code submission.
    The buffer needs to be able to grow, but cannot be owned by the
    Assembler because it has to survive until the code is submitted.

Also refactor the use in cctest.h to have less statically declared
constants. Instead, just create the set of extensions in the individual
tests.

b615dfa550 [torque] Implement methods and constructors for structs and classes
With the changes in this patch,	it is now possible to add methods to
both Torque's class and struct types. As a special case, "constructor"
methods are used to initialize the values of classes and structs when
they are constructed.

The functionality in this patch	includes:

- The refactoring of class- and struct-handling code to share field
  and method declaration code between both.

- Addition of the "%Allocate" intrinsic that allocates raw bytes to be
  allocated from the V8 GC's NewSpace heap as the basis for freshly
  created, initialized class objects.

- An implementation of a CallMethodExpression AST node that enables
  calling methods and constructors, including special handling of
  passing through the "this" pointer for method calls on structs by
  reference. The syntax for struct construction using "{}" remains as
  before, but now calls the struct's matching constructor rather than
  implicitly initializing the struct fields with the initialization
  arguments. A new syntax for allocation classes is introduced: "new
  ClassName{constructor_param1, constructor_param1, ...}", which
  de-sugars to an %Allocate call followed by a call to the matching
  constructor.

- class	constructors can use the "super" keyword to initialize	their
  super class.

- If classes and struct do not have a constructor, Torque creates a
  default constructor for them based on their field declarations,
  where each field's initial value is assigned to a same-typed
  parameter to the the default constructor. The default constructor's
  parameters are in field-declaration order, and for derived classes,
  the default constructor automatically uses a "super" initialization
  call to initialize inherited fields.

- Class field declarations now automatically create ".field" and
  ".field=" operators that create CSA-compatible object accessors.

- Addition of a no-argument constructor for JSArrays that creates an
  empty, PACKED_SMI_ELEMENTS JSArray using the machinery added
  elsewhere in this patch.
