There seems to be a bug in gcc which causes link errors after
this CL: https://crrev.com/c/3714238
Issue seems to happen when using default template argument
of function type. A related bug report on bugzilla:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105848
A workaround is to explicitly instantiate the template
for type <bool>.

If parsing fails in ScopeIterator::TryParseAndRetrieveScopes, the
intention was to fail silently (see the TODO there). However,
closure_scope_ being nullptr caused us to fail less silently.
This alone is not enough for fixing chromium:1316811 but the other
fixes needed are sufficiently unrelated.

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.

When the sandbox is enabled, an empty ArrayBuffer does not have a
nullptr backing store but instead points to a special EmptyBackingStore
pseudo-object inside the sandbox. This then requires special handling
during deserialization. This CL fixes two cases where this was not done
correctly, which caused some crashes when --stress-snapshot is active.

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.

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.
