d5f08e4e4f [api] Remove unowned Extensions interface
Extensions are now always passed via unique_ptr and are owned by V8.
This CL removes the deprecated API where the embedder would own the
Extension, but has no mechanism for deleting it.

Fixing a few float and int overflows.
Drive-by fix: with --experimental-wasm-bigint, Number values

the fix is to throw instead.

No regression test for 933103 because it will OOM anyway.

This CL also gives up trying to maintain double and system word
fields at aligned addresses because currently it's not always
maintained (v8:8875) and Torque object definitions do not support
padding fields (v8:8863).

Given that both platforms where pointer compression is going to be
enabled (x64 and arm64) support loading of doubles and full words
from 4-byte aligned addresses we are fine.

683cf6f43b [cleanup] Remove obsolete "one byte data hint" for strings.
In the early days of Chrome when we used WebKit there was no support for
ASCII strings on the C++ side, so we put a hint onto these two-byte
strings that said "string only contains one byte data", such that
internally in V8 when these were involved in string operations, we could
instead create the *cheaper* one byte strings.

Nowadays Blink properly supports one-byte string representations and
this additional hint only comes with overhead, since we check it in
quite a few places (i.e. on the hot path for string concatenation), plus
we end up consuming more memory due to the additional string maps.
Removing the hint also frees one bit in the InstanceType zoo for
strings.

This alone improves performance on the `bench-dom-serialize.js` test case
by around **3%**.

3f8b031647 [zone] Remove segment pooling from accounting allocator
This pooling introduces severe lock contention for Liftoff compilation,
since each compilation uses its own Zone which does at least one
segment allocation.
It's also unclear whether pooling improves performance, since {malloc}
should implement a similar pooling mechanism, but better optimized for
multithreaded uses.

Feel free to revert if this introduces significant regressions.

51e80efd12 [tracing] Fix races in TracingController implementation
The default TracingController (used by d8 and Node) has some concurrency
issues. The new test flushes these out, when a second thread logs trace
events while the main thread calls StopTracing().

- Use an acquire load in UpdateCategoryGroupEnabledFlags() because this
  was racing with GetCategoryGroupEnabled() where a new category is
  added in the slow path. g_category_groups is append-only, but
  reads/writes to g_category_index need to be correctly ordered so that
  new categories are added and only then is the change to the index
  visible. The relaxed load ignored this and caused unsynchronized
  read/write.
- Use a relaxed load in ~ScopedTracer() to access category_group_enabled
  as this previously used a non-atomic operation which caused a race
  with UpdateCategoryGroupEnabledFlag() which does a relaxed store.
- Replace TracingController::mode_ with an atomic bool as read/writes to
  mode_ were not synchronized and caused TSAN errors. It only has two
  states and it doesn't seem like we will extend this so just convert it
  to bool.
- Take the lock around calling trace_object->Initialize in
  AddTraceEvent(), and around trace_buffer_->Flush() in StopTracing().
  These two raced previously as the underlying TraceBufferRingBuffer
  passes out pointers to TraceObjects in a synchronized way, but the
  caller (AddTraceEvent) then writes into the object without
  synchronization. This leads to races when Flush() is called, at which
  time TraceBufferRingBuffer assumes that all the pointers it handed out
  are to valid, initialized TraceObjects - which is not true because
  AddTraceEvent may still be calling Initialize on them. This could be
  the cause of issues in Node.js where the last line of tracing/logging
  sometimes gets cut off. This is kind of a band-aid solution - access
  to the TraceObjects handed out by the ring buffer really needs proper
  synchronization which at this point would require redesign. It's quite
  likely we will replace this with Perfetto in the near future so not
  much point investing in this code right now.
- Enable TracingCpuProfiler test which was flaky due to these bugs.

f781f522af Re-detect the host time zone if requested by an embedder
Add an enum argument to DateTimeConfigurationChangeNotification to
control whether or not to redetect the host time zone. The default value
kSkip doesn't cause redetecting so that callers do not need to change if
they want the current behavior (e.g. Chromium).

Note that the host time zone detection does not work when v8 is run
inside a sandbox as in Chromium so that Chromium detects the host time
zone outside the sandbox before calling
DateTimeConfigurationChangeNotification. OTOH, other v8 embedders may
find it more convenient for v8 to do the host time zone detection on
their behalf. In that case, they can call the function with the new
argument set to value kRedetect.

Test:
With PHP+V8Js on linux, execute:
php -r '
  putenv("TZ=Europe/Helsinki");
  $v8 = new V8Js();
  $v8->executeString("print((new Date(0)).toString()+\"\\n\");");
  putenv("TZ=America/New_York");
  $v8->executeString("print((new Date(0)).toString()+\"\\n\");");'

After this:
 * MicrotaskPolicy is per-MicrotaskQueue rather than single global one.
 * ENTER_V8 runs MicrotaskQueue associated to the current Context, rather
   than the default_microtask_queue().
 * SuppressMicrotaskExecutionScope and MicrotasksScope are ready to
   take MicrotaskQueue parameter, rather than using the default one.

Note that there's no way to use a non-default microtask queue until we
expose it as a V8 API.

648ba1f7dd Defer inferring language mode for PropertyCallbackInfo
This cl: https://chromium-review.googlesource.com/c/v8/v8/+/1421077
changed the implementation of SetProperty to infer the language mode.
Language mode is only required when there is an error to decide if we
have to throw an error or not. However we used to compute language mode
eagerly for PropertyCallbackInfo. This causes regressions in some
benchmarks. This cl changes it by deferring it further by computing
it only when it is actually required.

76c9368593 [api, global-handles] Add TracedGlobal
TracedGlobal integrates with the use case of EmbedderHeapTracer and replaces
regular weak Global or Persistent nodes for such cases. This allows to simplify
the case for regular weak handles in a sense that they follow regular weak
semantics (if the underlying object is otherwise unreachable the weak handle
will be reset).

TracedGlobal requires slightly different semantics in the sense that it can be
required to keep them alive on Scavenge garbage collections because there's a
transitive path that is only known when using the EmbedderHeapTracer.
TracedGlobal accomodates that use case.

TracedGlobal follows move semantics and can thus be used in regular std
containers without wrapping data structure.

The internal state uses 20% less memory and allows for only iterating those
nodes when necessary. The design trades the virtual call when iterating
interesting persistents in the GC prologue with calling out through the
EmbedderHeapTracer for each node which is also a virtual call. There is one less
iteration over the set of handles required though and the design is robust
against recursive GCs that mutate the embedder state during the prologue
callback.
