b2d8bfc793 [heap] Fine-grained JSArrayBuffer tracking
Track based on JSArrayBuffer addresses instead of the attached backing store.
This way we can later on iterate buffers on a single page. The reland also
switches to a page-based implementation where a page contains the set of its
contained (live and dead) buffers.

Details of tracking:
- Scavenge: New space pages are processes in bulk on the main thread
- MC: Unswept pages are processed in bulk in parallel. All other pages
  are processed by the sweeper concurrently.

a6da98d86f Introduce a new phantom weakness type without finalization callback.
Handles of this type are automatically reset by the garbage collector
when their objects are not longer reachable.

The motivation is to reduce pause time of external.weak_global_handles
phase of the garbage collector by not maintaing the list of pending
callbacks and not calling the callbacks.

Local testing on discourse page of the v8.inifinite_scroll benchmark
shows 7x improvement for this GC phase.

Before:
external.weak_global_handles
 len: 21
 min: 0.0
 max: 4.5
 avg: 0.757142857143

After:
external.weak_global_handles
 len: 21
 min: 0.0
 max: 0.5
 avg: 0.109523809524

A follow-up patch will enable the new phantom handles in Chromium.

d1fb8384e0 [turbofan] Introduce Oddball::to_number_raw and use it for change lowering.
The Oddball::to_number_raw field contains the actual double value of the
Oddball converted to a number, and is located at the same offset as the
HeapNumber::value field, so for lowering changes we don't need to check
for undefined (or any other oddball explicitly).

39939eebf8 Remove isolate arg from EmbedderHeapTracer methods.
As the code on the blink side sits down, we realize we don't need isolate arg
anymore. As the heap tracer is set per isolate, it can actually be confusing if
the isolate passed as argument is always the same as the isolate the heap tracer
was set for. Wdyt?

97e3909a53 [api] Deprecate *MemoryAllocationCallback
To keep track of memory characteristics of a JS program use
GetHeapSpaceStatistics from a combination of
- a GC epilogue callback registered using AddGCEpilogueCallback
- an interrupt registered using RequestInterrupt

Rationale:
The feature is currently broken as those callbacks are (also) executed from
background threads, breaking our implicit contract for only performing callbacks
on the foreground thread. Furhtermore, it's not clear for the embedder whether
these allocations originate in JS, or are required for a GC.

Note:
- The already deprecated non-isolate versions are removed with this CL.

6d1f7282af Use EmbedderHeapTracer instead of object grouping when embedder sets the heap tracer.
When the embedder sets the heap tracer, V8, during marking, will collect all reachable wrappers, and then ask embedder to trace its heap. The embedder is expected to call PersistentBase::RegisterExternalReference with all wrappers reachable from the given ones. This fixed point iteration happens in MarkCompact::ProcessEphemeralMarking.

For more efficient object visiting during marking, we need a special JS_API_OBJECT_TYPE (in tandem with already existing JS_SPECIAL_API_OBJECT_TYPE) and corresponding visitor (JSApiObjectVisitor).

d2eb555ee1 Use a dictionary-mode code cache on the map rather than a dual system.
The previous code cache system required stubs to be marked with a StubType, causing them to be inserted either into a fixed array or into a dictionary-mode code cache. This could cause names to be in both cases, and lookup would just find the "fast" one first. Given that we clear out the caches on each GC, the memory overhead shouldn't be too bad. Additionally, the dictionary itself should just stay linear for small arrays; that's faster anyway.

This CL additionally deletes some dead IC code.

2a1570ef1a Temporarily undeprecate ForceSet
I first need to figure out what to do about window.document before we
can deprecate this: window.document is a regular accessor, however, once
the window navigated from about:blank, its value will never change.
Blink uses ForceSet to then replace the accessor with a data constant
which has way better performance than invoking the accessor all the
time.

Since the accessor, however, is installed as read only &
non-configurable, there is no spec compliant way to pull this off right
now

91d344288a Parser: Make skipping HTML comments optional.
API change: This adds a new flag skip_html_comments to v8::ScriptOriginOptions. This flag controls whether V8 will attempt to honour HTML-style comments in JS sources.

(That is: Gracefully ignore <!-- ... ---> in JS sources, which was a popular technique in the early days of JavaScript, to prevent non-JS-enabled browsers from displaying script sources to uses.)

The flag defaults to 'true' when using v8::ScriptOrigin constructor, which preserves the existing behaviour. Embedders which are happy with the existing behaviour will thus not need any changes.

f507bc1c72 [serializer] Add API to warm up startup snapshot with an additional script.
A startup snapshot is considered cold when it does not contain any
function code. We can now create a warm startup snapshot from a cold one
by running a warm-up script. Functions exercised by the warm-up script
are compiled and its code included in the warm startup snapshot. Side
effects caused by the warm-up script does not persist.

4ea11ca941 Add UseCounters for various RegExp compatibility issues
We have compatibility workarounds to return 'undefined' on accessors
to RegExp.prototype. This patch adds two UseCounters for two categories
of this non-spec-compliant path:
- source
- ignorecase, multiline, global

9a1387f6a9 Introduce v8::MicrotasksScope.
This scope is used to control microtasks execution when MicrotasksPolicy::kScoped is engaged.

Attempt #2. First one was reverted due to chromium breakage: SetAutorunMicrotasks(false) was broken.

10f6a9e62b Use a different GCCallbackFlag for GCs triggered by CollectAllAvailableGarbage
Blink wants to distinguish GCs triggered by CollectAllAvailableGarbage
from GCs forced by testing. This CL introduces a new flag to differentiate
the two GC types.
