Original Commit Message:

    New trace events:

    - finished OSR compilation.
    - entry into OSR code.

    Since the latter now happens without a trip into runtime, tracing is a
    bit more involved - we need to check FLAG_trace_osr in generated code,
    and call a runtime function if it is set.

Multiple code spaces are cheaper on 32-bit systems, because we can
directly call between them. Over-reservation on the other hand increases
the chance for OOMs. Hence reduce the code space estimation (used for
the initial reservation) on 32-bit systems.

Numbers were obtained from an older Epic module, Photoshop, and AutoCAD.
I'll keep an eye on the {V8.WasmModuleNumberOfCodeSpaces} counter.

This is a reland of https://chromium-review.googlesource.com/c/v8/v8/+/3607389.
The previous revert is https://chromium-review.googlesource.com/c/v8/v8/+/3610448.
Reason for revert: https://crbug.com/v8/12838.

The original CL has merge conflicts and cannot be relanded,
so this CL is newly opened.

This CL moves cctest/test-log to unittests/logging/log-unittest
, fixes the flaky tests in https://bugs.chromium.org/p/v8/issues/detail?id=12838 and updates the unittests status for log-unittest.


Flaky Tests:
- https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20TSAN%20-%20stress-incremental-marking/7287/overview
  - flaky LogTest.Issue539892 is caused by in stress-incremental-marking
    mode, Heap::MarkCompact will trigger CodeMovingGCEvent in https://source.chromium.org/chromium/chromium/src/+/main:v8/src/heap/heap.cc;l=2586;drc=52f06e6b43ff95eccf79e0a5df8d4d83c029130a for
    FakeCodeEventLogger which was already destructed
    when Heap::PerformGarbageCollection task was handled in
    DefaultPlatform::PumpMessageLoop. This should be fixed by removing
    FakeCodeEventLogger in LogTest.Issue539892.

  - flaky LogTest.LogAccessorCallbacks is caused by the data race in
    Sampler::DoSample. This should be fixed in https://chromium-
    review.googlesource.com/c/v8/v8/+/3616429.

-https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20TSAN/41327/overview
  - flaky LogTest.ExternalLogEventListenerWithInterpretedFramesNativeStack
    is caused by the data race of i::FLAG_* which were written again after
    setting up the isolate. This should be fixed by only writting
    i::FLAG_* before setting up the Isolate.

- https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64/47277/overview
  - flaky LogTest.BuiltinsNotLoggedAsLazyCompile is caused by the data

... Profiler::Remove.

In Profiler::Insert and Profiler::Remove, TSAN cannot
figure out that when head_ and tail_ equals, Profiler::Insert
will always execute before Profiler::Remove, and tsan
will report data race between buffer_[head] write and
buffer_[base::Relaxed_Load(&tail_)]. This CL changes the
tail_ atomic load and store memory order to gurantee that
buffer_ read and write always after and before tail_ load
and store, which gives tsan more constraint.

There are currently several flags to tune V8's optimisation level:
  --sparkplug, --maglev, --opt

This CL tries to make this simpler by introducing yet another flag.
--max-opt limits the maximum optimisation tier and avoids the common
error to mistake --no-opt with no dynamic optimisations.

Settings:
  --max-opt=999 Allow all optimisations, default configuration.
                Any number > 3 will do, as long as no other tier will be
                added.
  --max-opt=0   Allow only ignition
  --max-opt=1   Allow up to sparkplug
  --max-opt=2   Allow up to maglev
  --max-opt=3   Allow up to turbofan

concurrent transitions of strings happening anymore.

- Remove String migration sentinel maps + helper methods
- Remove CanMigrateInParallel()
- Remove MigrateStringMapUnderLockIfNeeded() and simplify MakeThin()

There is still unused code I didn't remove in this CL, as we might need
it later for shared struct features: YIELD_PROCESSOR for spinlocks and
Relaxed_Memcmp().

The no_condition / kNoCondition not only has the flaw that it's a
special case which represents an illegal / nonexisting condition, and
thus needs special handling in all methods which get a condition as
input (this check is often missing), it is also weird in that every
negative condition value must be considered a "no condition".

It turns out that this "no condition" is rarely used, and can easily be
avoided by duplicating methods, or storing a {base::Optional<Condition>}
instead (not needed anywhere yet).

This is a follow-up to https://crrev.com/c/3629553.
