0b95f282f7 Introduce Isolate::ClearCachesForTesting API method
This CL adds a new method intended for tests or lab settings to
cleanup V8 caches. The synchronous nature of the method greatly reduces
flakiness of blink leak detection in many cases.

This reverts commit 7ef67b2e9e.

Reason for revert: Speculative revert for a blocked roll - https://chromium-review.googlesource.com/c/chromium/src/+/2947365

Original change's description:
> heap: Fix initial GC configuration for C++-only heaps
>
> Heaps in V8 start with a large limit that is shrunk upon young
> generation GCs, based on some liveness estimate. This provides best
> throughput during startup while at the same time finding a reasonable
> first limit.
>
> For C++ (embedder memory) there is no estimate which is why it was
> piggy-backing on V8. This breaks in scenarios where no JS memory is
> allocated.
>
> In this fix we start a memory reducer after embedder memory has hit
> the activation threshold if no GC happened so far. As soon as a single
> Scavenger has happened, we leave it up to the JS estimate to figure
> out a limit. Memory reducing GCs will then find a regular limit based
> on the initial live size.
>
> Drive-by: Give embedders the same activiation threshold of 8MB as JS.

9bfd401ef5 [compiler] RawFastPropertyAt without serialization
This is a step towards making JSObjectRef non-serialized.

Change JSObjectRef::RawFastPropertyAt to use a direct load with
relaxed semantics. Special handling of `uninitialized` sentinel values
is moved to the only use-site.

A new lock `boilerplate_migration_access` protects against concurrent
boilerplate migrations while we are iterating over properties.

363ab5ae71 [regexp] Propagate eats_at_least for negative lookahead
In issue 11290, we disabled the propagation of EAL data out of
lookarounds, because it was incorrect for lookahead nodes in
loops. This caused performance regressions: for example,
`/^\P{Letter}+$/u` (matching only characters that are not in Unicode's
Letter category) uses negative lookahead when matching lone
surrogates, and became about 2x slower. I spent some time looking into
fixes, and this is what I've settled on.

Some background: the implementation of lookarounds in irregexp is
split between positive and negative lookaheads. (Lookbehinds aren't
relevant here, because backwards matches always have EAL=0.)  Positive
lookaheads are wrapped in BEGIN_SUBMATCH and POSITIVE_SUBMATCH_SUCCESS
ActionNodes. BEGIN_SUBMATCH saves the current state.
POSITIVE_SUBMATCH_SUCCESS restores the necessary state (while leaving
any captures that occurred during the lookaround intact).

Negative lookaheads also begin with a BEGIN_SUBMATCH node, but follow
it with a NegativeLookaroundChoiceNode. This node has two successors:
a lookaround node, and a continue node. It only executes the continue
node if the lookaround node backtracks, which automatically restores
the previous state. Negative lookarounds also can't update captures.

This affects EAL calculations. It turns out that negative lookaheads
are already doing the right thing: EatsAtLeastPropagator only
propagates information from the continue node, ignoring the lookaround
node. The same is true for quick checks (see the comment in
RegExpLookaround:Builder::ForMatch). A BEGIN_SUBMATCH for a negative
lookahead can simply propagate the EAL data from its successor like
any other ActionNode, and everything works.

Positive lookaheads are harder. I tried saving a pointer to the
successor in BEGIN_SUBMATCH, but ran into problems in FillInBMInfo,
because the EAL value corresponded to the nodes after the lookahead,
but the analysis was still looking at the nodes inside. I fell back
to a more modest approach: split BEGIN_SUBMATCH in two, and propagate
EAL info for BEGIN_NEGATIVE_SUBMATCH while keeping the current
behaviour for BEGIN_POSITIVE_SUBMATCH. This fixes the performance
regression at hand.

Two potential approaches for fixing EAL for positive lookahead are:
 1. Handling positive lookahead with its own dedicated choice node,
    like NegativeLookaroundChoiceNode.
 2. Adding an eats_at_least_inside_loop field to EatsAtLeastInfo,
    which is <= eats_at_least_from_possibly_start, and using that
    value in EatsAtLeastFromLoopEntry.

Both of those approaches are more complex than I want to tackle
right now, though.

09faa661ea Reland "[csa] Remove InnerAllocate and replace with non-folded allocations"
The initial CL is suspected to break the --predictable CI.
But looks like the CI is still crashing and also flaky after the
revert. So reland it again.

This is a reland of 59d58d722e

Original change's description:
> [csa] Remove InnerAllocate and replace with non-folded allocations
>
> This CL removes all uses of InnerAllocate (except memento allocations)
> and replace with non-folded allocations. The change is based on the
> fact that 1. Those InnerAllocates are not guarded by --allocation-folding
> flag. 2. Hopefully the MemoryOptimizer can handle the folding and no
> performance regression will happen.
>
> Two special versions of InnerAllocate is still kept:
> * One for memento allocations (renamed to InnerAllocateMemento).
> * One for AllocateUninitializedJSArrayWithElements (renamed to InnerAllocateElements).

7ef67b2e9e heap: Fix initial GC configuration for C++-only heaps
Heaps in V8 start with a large limit that is shrunk upon young
generation GCs, based on some liveness estimate. This provides best
throughput during startup while at the same time finding a reasonable
first limit.

For C++ (embedder memory) there is no estimate which is why it was
piggy-backing on V8. This breaks in scenarios where no JS memory is
allocated.

In this fix we start a memory reducer after embedder memory has hit
the activation threshold if no GC happened so far. As soon as a single
Scavenger has happened, we leave it up to the JS estimate to figure
out a limit. Memory reducing GCs will then find a regular limit based
on the initial live size.

Drive-by: Give embedders the same activiation threshold of 8MB as JS.

ca05c5a2e5 Add TryGetCurrent() method to v8::Isolate
This commit adds a TryGetCurrent() method to the v8::Isolate class.

The motivation for adding this method this is that in Node.js we've run
into situations where we need to check if there is a current
Isolate and we are using GetCurrent() for this. The issue is that for a
debug build of Node.js, the debug check in GetCurrent() will cause a
failure.

The suggestion in this changeset is to allow getting the current
Isolate, or null if one does not exist, without any checks.

82b673bcbc Fix counting ignition dispatches
The flag --trace-ignition-dispatches has been broken for a long time,
since it was not designed to work with bytecode handlers that are
generated ahead of time by mksnapshot. This splits the existing
--trace-ignition-dispatches logic into two separate parts:

1. A gn argument which instructs mksnapshot to include dispatch counting
   in the bytecode handlers, and ensures that the Interpreter allocates
   the array of counters, and
2. A runtime flag which enables the ignition-statistics extension which
   implements the JS-accessible function getIgnitionDispatchCounters().
