The spec uses the CreateDataProperty abstract operation to add
properties to the result object of Object.fromEntries.

Confusingly, the FastCreateDataProperty Torque macro is special-cased
for adding array element properties instead of generic keyed properties.
The slow path for FastCreateDataProperty goes to runtime, which was
being hit everytime in Object.fromEntries since the result object is not
an array.

This CL switches to using StorePropertyInLiteral instead, which
corresponds to the CreateDataProperty spec operation, and also has fast
paths that stay in CSA.

There are two different limits for the maximum memory size in
WebAssembly:
1) A 4GB limit which is the same on all platforms, and is observable for
JS programs. It is used to limit the allowed declared maximum size of a
wasm memory.
2) A potentially lower limit (2GB on 32-bit systems, 4GB otherwise)
which can be further limited using a command-line flag. This limit is
used whenever actually allocating or growing a wasm memory. This limit
is not directly observable, but we make sure that no wasm memory will
ever be bigger than this limit.

The second limit is the one we should check against when allocating or
growing memory, while the first limit should be used when validating
a module (or the parameters for WebAssembly.Memory). The compiler can
rely on no memory being bigger than the second limit, which again is
never bigger than the first limit.

This CL adds some more documentation to the two limits, and cleans up
all usages.
This also makes {kPlatformMaxPages} and {kMaxMemoryPagesAtRuntime}
obsolete.

This is a reland of 5ef4e14f

The previous CL caused flaky test failures with some concurrent
allocation tests. The reason for this was that the main thread's state
and collection_requested_ can't be updated in an atomic operation
anymore.

Any thread will now invoke RequestGC() first. Then it will wait in
AwaitCollectionBackground() when the main thread was running. Both
methods can and will be invoked more than once.

The new flag block_for_collection_ is used to decide whether a thread
needs wait for the GC. collection_requested_ can't be used for that
purpose because that flag is also true when the main thread is parked.

Original change's description:
> [heap] Replace usages of CollectionRequested with SafepointRequested
>
> CollectionRequested was used exclusively on the main thread when a
> background thread requested a GC. The main thread never used
> SafepointRequested at any time. Now with the shared GC we might need to
> stop multiple isolates in a safepoint in the future. In such a situation
> we would need to use SafepointRequested also on the main thread.
>
> This CL prepares V8 for this situation by using SafepointRequested
> instead of CollectionRequested and friends on the main thread. The slow
> path of Safepoint(), Park() and Unpark() will check in the future
> whether the main thread needs to halt for a shared GC or needs to
> perform a local GC. At the moment, simply performing the local GC is
> still enough.

The test has a loop that allocates large objects until it gets an
allocation failure. The test then asserts that the subsequent allocation
should also fail. That however does not necessarily hold because the
previously allocated objects may be collected to free up the space.

This change creates a handle for each allocated object. It also
restricts the size of the heap to 20MB to reduce memory consumption.

Following up on https://crrev.com/c/1946349, this moves the blocklist to
the ScopeInfo instead of storing it directly on the DebugEvaluate
contexts. This is not the final state that we're looking for, but a
small step along the way.

CallWithArrayLike was optimized in TF only for 'arguments' in inlined
functions. Here we add logic to optimize also in non inlined functions,
enabling the rewriting of Function.prototype.apply(f, [1, 2, 3])
as f(1, 2, 3).

This is a reland of 2c096b53

Relanding as-is. Reason for reland: was speculatively reverted.

Original change's description:
> [codegen] Add TSAN support for tagged stores in generated code
>
> Mimics the kArchStoreWithWriteBarrier store in generated code by having
> a relaxed store to the same address, with the same value. This is done
> in order for TSAN to see these stores from generated code.
>
> Since it is done only for kArchStoreWithWriteBarrier TSAN will see
> tagged stores only.

In WasmCapiCallWrappers, the address is passed in a register instead
of as an immediate, so we reduced 3 instructions to load the address
to t9;
