The WasmInstanceObject stores two new arrays:
- imported_mutable_globals_buffers_: a FixedArray of all the imported
globals' array buffers.
- imported_mutable_globals: a calloc'd array of Addresses pointing to
the mutable global in its array buffer.
When accessing the global, the generated code looks up the address in
imported_mutable_globals to find where to load/store.

The mutable-globals proposal spec allows importing as Numbers or
WebAssembly.Global values, but always exports as WebAssembly.Global.
Since the value is always boxed, we can also import/export i64 values.
This CL also includes support for export of mutable globals. Since the
underlying ArrayBuffer that stores the global's value is shared between
the module and the WebAssembly.Global object, all that needs to be done
is remove the validation check.

I missed one required change which was hidden behind an #if. The fix is in
the diff between Patch 1 and Patch 3.
Original message:
In this CL I remove the isolate from signatures of ExternalReference
accessor functions where the isolate is not used. The uses of the
isolate were already removed in previous CLs.
Changes:
* I split the ExternalReference list in external-reference.h into
those which need the isolate for initialization and those which do not.
* I removed the public constructors and replaced them by
ExternalReference::Create(). The reason is to separate external
creation more clearly from internal creation, because externally
created ExternalReferences sometimes need redirection, whereas
internally created ExternalReferences are just stored as they are.
In addition, by removing the isolate from the signature of the
public constructors, they suddenly exactly matched the interal
constructor.
* Replace all uses of the public constructors with
ExternalReference::Create().
* Remove the isolate from all call sites where necessary.
This is a step towards making WebAssembly compilation independent of
the isolate.

This CL implements TypedArray.p.sort in Torque. The Torque
version works basically the same as the existing JS builtin:
When no comparison function is provided, the C++ fast path builtin
is used. Otherwise a quicksort written in Torque is used, with
a InsertionSort fallback for smaller arrays.
The JS quicksort implementation also containes a more elaborate
third pivot calculation for larger arrays. This is currently not done.
Reported benchmark results are only for those, where a custom
comparison function is provided. The numbers for the C++ path stayed
the same.

with Turbofan, and replace the Liftoff-compiled code as soon
as Turbofan finished compilation, thus achieving high performance.

WebAssembly.instantiate is polymorphic, it can either take a module
object as parameter, or a buffer source which should be compiled first.
To share code between the two implementations, the module object was
first passed to a promise (i.e. which is the result of compilation).
However, passing the module object to a promise has a side effect if
the module object has a then function. To avoid this side effect I
remove this code sharing and call AsyncInstantiate directly in case
the parameter is a module object.

At the moment, the isolate is allocated and initialized in a single
step. This has the downside that the platform cannot register the
isolate before the isolate gets initialized, and therefore the platform
is not available for the isolate during initialization. With this CL we
register the uninitialized isolate on the platform and initialize the
isolate after that.
This change is needed to allow the creation of task runners already
during the initialization of the isolate.

Instead of passing multiple pointers to input and output, or to two
input values, just pass one pointer which holds all inputs and where
the output is written.
This also reduces the size of generated Turbofan graphs, since only one
stack slot is needed and less arguments are passed to the call.
It also fixes undefined behaviour, since we were passing a pointer e.g.
as {uint64_t*}, but accessed it using {ReadUnalignedValue}. Now we pass
an Address, which does not have any alignment constraints.

This makes testing with random gc stress use the status file entrees
for gc fuzzing as well, since many test cases not suitable for one, are
not suitable for the other.
This also skips two more tests that rely on assert(Un)Optimized, which
is unreliable with gc fuzzing.

The memory metric samples memory usage immediately after forcing GC via
LowMemoryNotification. This makes the metric sensitive to the unmapper
tasks timing.
This patch forces eager unmapping in CollectAllAvailableGarbage.
It also forces eager unmapping of non-regular chunks at the beginning
of Mark-Compact to avoid accumulation of non-regular chunks.

These functions are now unused within V8, as we need tighter control in
mksnapshot for creating embedded.cc.
Embedders should switch to using SnapshotCreator directly.

The handling of wasm breakpoints was prone to forget previously set
breakpoints when inserting new ones. In particular, adding breakpoints
in reverse order or adding more than 4 breakpoints would fail.

ScavengeExternalString and ScavengeExternalOneByteString clear GC flags,
which confuses concurrent sweeping that was started from another test.
Tests that mutate flags should not be threaded.
