Part of the GetObjectProperties test case is for verifying the human-
readable brief object description string that GetObjectProperties
returns. That string might look something like this:

"xy" (0x28f038d5 <v8::internal::SeqOneByteString>)

GetObjectProperties also tries to detect known immortal objects by
recognizing their addresses, which is useful in crash dumps with limited
memory. The recognized object name, if it exists, is prepended to the
description string. In order to provide this data accurately (in builds
without pointer compression), GetObjectProperties relies on the caller
to provide the addresses of the first pages in read-only space, map
space, and old space. If the caller doesn't provide those addresses,
then GetObjectProperties does the best it can with limited information
and reports possible matches based on an object's offset within the heap
page that contains it. So the result string might look like this, if the
object happened to get allocated at a lucky offset within its page:

maybe LoadHandler3Map "xy" (0x28f038d5 <v8::internal::SeqOneByteString>)

As a result, when testing these descriptions, we should generally check
that they contain the interesting data rather than that they start with
it, because some incorrect "maybe" match with a known object might be
included at the beginning.

Factors out the group regexes from callstats.py so the two tools can
share them. When --group is specified, the stats are grouped together
using the callstats.py groupings. Also adds --filter (can be supplied
multiple times) to only show certain groups.

Under the hood, this converts the simple arrays and dictionaries to use
classes to simplify the code somewhat.

This allows arbitrary expressions to specify the length of an array.
These expressions get access to globally declared things and the
preceding fields of the current object.
Unfortunately, this breaks generated C++ runtime code, so as a
workaround, I special-case expressions that are just an identifier
and handle them as before. We might want to support more cases there
in the future, probably also with special-casing since having a full
C++ back-end for Torque is infeasible.

This unifies marking worklists handling by the main thread marker and
by the concurrent markers. A new class called MarkingWorklistsHolder
owns all marking worklists: the default worklist, the on-hold worklist,
and the embedder worklist. Each thread creates a local view of the
marking worklists by creating an instance of MarkingWorklists.

Additionally, marking visitors now work on MarkingWorklists instead of
accessing each worklist individually.

Besides cleaning the code up, this CL provides a bottleneck for
implementing per-context worklists.

Add VTune domain support extension to use VTune Domain/Task API and
tagging trace data for particular JS code block.

How to use:
1. Set `"checkout_ittapi" = True` in the custom_vars section of .gclient
file to download intel/ittapi by 'gclient sync'
2. Build d8 with gn build flag 'v8_enable_vtunetracemark = true'
3. Run d8 with flag '--enable-vtune-domain-support'

The Vtune Domain/Task API can be invoked from JS to mark JS code block.
You can mark the start of a JS task by
    vtunedomainmark(domain_name, task_name, "start")
and the end of a task by
    vtunedomainmark(domain_name, task_name, "end")
Tasks can nest.

The VTune API (ittapi) is integrated as an external third party library
while the v8_vtune_jit also relies on the VTune ittapi. We have another
patch almost ready which refactors the v8_vtune_jit related code to
depend on the third_party/ittapi. We will submit the refactored v8_vtune_jit
code after this patch stabilized and landed.

Add a method to set the URL of a Wasm script from a WasmStreaming object.
This will allow devtools to report the actual URL when it is available.
