TrapIf and TrapUnless had an effect input, but not an effect output.
This is not canonical for Turbofan graphs. This CL puts them properly
into the effect chain.

Drive-by:
- Remove premature optimization in WasmGraphBuilder::TrapIfEq{32,64}.
- Change LoadFromObject to Load when loading from a stack slot.

A lot of logic is missing from the Wasm entry for fast api calls.
The majority of the lowering is shared between wasm and js, and uses
the same graph operators, so this adds a common fast api call builder
which can be called from the wasm compiler and the js compiler.

With recent changes, we resolve the promise of e.g. WebAssembly.compile
with the external API, and not the V8-internal API. The external API,
however, also handles microtasks, and depending on the MicrotasksPolicy,
may also execute microtasks immediately. This means the then-handler of
WebAssembly.compile may get executed within all the scopes that were
open when the external API was called. One of the open scopes is the
CancelableTask that finishes WebAssembly compilation.

The deadlock seen in the issue arises now when {quit()} gets called in
the then-handler of WebAssembly compilation.  The reason is that
{quit()} terminates the isolate, and during isolate termination, we wait
for all running CancelableTasks to finish. This, however, means a
deadlock, because the task that terminates the isolate is waiting for
itself to finish.

SourceTextModule::ExecuteAsyncModule asserts the execution of
the module's async function to succeed without exception. However,
the problem is that TerminateExecution initiated by embedders is
breaking that assumption. The execution can be terminated with an
exception and the exception is not catchable by JavaScript.

The uncatchable exceptions during the async module evaluation need
to be raised to the embedder and not crash the process if possible.

Recently perfetto introduced `perfetto::DynamicString` to allow clients
to wrap dynamic event name strings. So that clients don't have to
manually set event name inside trace lambda.

With that:

TRACE_EVENT("cat", nullptr, [&](EventContext ctx) {
  ctx.event().set_name(dynamic_name_str)
});

is simplified to:

TRACE_EVENT("cat", perfetto::DynamicString{dynamic_name_str});

In this change we are making use of perfetto::DynamicString to pass
dynamic event name string.

This CL introduces a compile flag v8_enable_inner_pointer_resolution_osb
behind which lies the experimental implementation of the object start
bitmap. It disassociates the object start bitmap from the compile flag
v8_enable_conservative_stack_scanning. At the moment the former flag is
a prerequisite for the latter, as conservative stack scanning requires
some mechanism for inner pointer resolution and the object start bitmap
provides one such mechanism.

ICU 71 added new enum value UNUM_APPROXIMATELY_SIGN_FIELD
need to map to "approximatelySign"

We also discover a spec bug in
https://github.com/tc39/proposal-intl-numberformat-v3/issues/99

All the parts of formatRangeToParts should have a source "shared" for
the case that start and end are the same or very close.

Initial implementation for concurrent shared arrays. Current implementation exposes a `SharedArray` constructor, but its syntax might
change in the future.

Shared arrays can be shared across Isolates, have a fixed size, have no
prototype, have no constructor, and can only store primitives, shared structs and other shared arrays. With this CL shared structs are also allowed to store shared arrays.

The Backing storage for the SharedArrays is a `FixedArrayBase`. This CL introdces a new ElementKind: `SHARED_ARRAY_ELEMENTS`. The new kind should match the overall functionality of the `PACKED_SEALED_ELEMENTS` kind, but having it as standalone kind allows for easier branching in CSA and turbofan code.

Creates a feature (flag): transition from Done -> Wait
schedules a timer after 30s instead of 8s.
In local benchmark, this reduces by 50% cpu time spent doing
incremental marking and sweeping.
