In the previous refactoring --filter was accidentally filtering out
paths that matched <regexp>. This CL restores the original behavior
where only the matching paths are kept.

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 adds a typedef for LegacyOOMErrorCallback, which is identical to
OOMErrorCallback. Embedders will need to switch to
LegacyOOMErrorCallback so that we can change the definition of
OOMErrorCallback (see https://crbug.com/1323177).

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.

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.

Drive-by: Slightly reorganize other OSR tracing.

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

With the introduction of the StringForwardingTable, there are no
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.

Those conditions are rarely used and not properly supported everywhere.
If needed, we should duplicate methods instead, or pass a
{base::Optional<Condition>}.

Added IR members:
For updating the interrupt budget: Jump, JumpLoop, Return and
JumpFromInlined apply a delta to the interrupt budget.  For OSR:
JumpLoop needs its loop depth and the feedback slot (where cached OSR
code lives).

This CL also adds code to maintain the interrupt budget in ML code.

Future tasks are documented in TODOs.

- Repurpose flag `treat_global_objects_as_roots` when taking a heap
  snapshot for toggling whether internals should be exposed (to
  `hide_internals`).
- Use the toggle in creating heap snapshots for exposing class names
  as object names for C++ objects that have not explicitly been given a
  name.
