Embedded builtins are now unconditionally enabled, which removes the
need to differentiate between enabled/disabled embedded builtins.
This Cl removes the 'embedded_builtins' variant and related

This CL removes the 'v8_enable_embedded_builtins' GN argument and sets
the 'V8_EMBEDDED_BUILTIN' define unconditionally.
Removing the now obsolete 'define' and corresponding C++ code will be

The natives blob was deprecated in V8 7.8. This CL removes all related
functionality, including:
- Build system support, i.e.: generation of natives_blob.bin and the
v8_extra_library_files gn flag.
- Related scripts (js2c.py, concatenate-files.py).
- Related API functions (SetNativesDataBlob,
InitializeExternalStartupData).
- Natives bootstrapping logic.
- The InternalArray type (previously exposed through natives).
- Other natives-exposed builtins.
- Inlining of these builtins.
- The dedicated 'uncached external one byte string' type.
Step 1 landed in https://crrev.com/c/1824944.
Step 2 landed in https://crrev.com/c/1835536.
Step 3 (this CL) removes these all functionality related to natives
support in V8.

Also, when they were snapped, the right resizer totally obscured

mmap behaves differently on Windows. This change adjust how grokdump.py
uses it so that the script will run on Windows.
The disassembly doesn't work due to lack of /usr/bin/objdump - fixing
that is out of scope for this change. The output is still useful even
without the disassembly.

This CL removes the extension slot from contexts that don't need
them, hence reducing memory.
The following contexts will still have an extension slot: native,

This is a reland of c7c47c68f2.
This makes TSAN happy in addition to:
Previously I presumed that the context read from a frame in the profiler was
a valid context. Turns out that on non-intel we're not guaranteed that the
frame is properly set up. In the case we looked at, the profiler took a
sample right before writing the frame marker indicating a builtin frame,
causing the "context" pointer from that frame to be a bytecode array. Since
we'll read random garbage on the stack as a possible context pointer, I made
the code reading the native context from it a little more defensive.

The top bar was being scrolled down since the whole viewpane was
scrollable. It will now work in the way the "Dissasembly" tab
works: the content is scrollable, but not the pane.
This change makes Schedule and Sequence consistent within the

As a drive-by fix, remove some unused constants.

This change extends v8_debug_helper to export a new method that returns
a list of all known heap object types.
Why? We can substantially improve the user experience in our work-in-
progress WinDbg extension if we register handlers not only for
v8::internal::Object but for every specific HeapObject type. This has
two benefits:
- You save a click: if you're expanding a local variable of a more
specific type than Object, you can see properties immediately rather
than first needing to expand a sub-item that casts the variable to
Object.
- You retain the type hint: GetObjectProperties accepts a type hint
string, and it's super important to pass it when working in a crash
dump because the object's Map is probably inaccessible. If we have to
cast to Object first, we lose this data.

Symbol and *String classes are now declared on Torque with
generateCppClass, which means they don't use macro accessors anymore. As
such, the gen-postmortem-metadata script is not able to automatically
detect fields for those classes. Define metadata for those fields
manually for now. In the future we might want to generate it from Torque
for consistency.
Also renamed a few *String fields metadata to match the expected format
(className__fieldName__fieldType). For more context:

Design doc:
https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit
Changes from the design doc:
- Changed to use 'class' declarations rather than 'type' declarations
for things that need instance types but whose layout is not known to
Torque. These declarations end with a semicolon rather than having a
full set of methods and fields surrounded by {}. If the class's name
should not be treated as a class name in generated output (because
it's actually a template, or doesn't exist at all), we use the
standard 'generates' clause to declare the most appropriate C++ class.
- Removed @instanceTypeName.
- @highestInstanceType became @highestInstanceTypeWithinParentClassRange
to indicate a semantic change: it no longer denotes the highest
instance type globally, but only within the range of values for its
immediate parent class. This lets us use it for Oddball, which is
expected to be the highest primitive type.
- Added new abstract classes JSCustomElementsObject and JSSpecialObject
to help with some range checks.
- Added @lowestInstanceTypeWithinParentClassRange so we can move the new
classes JSCustomElementsObject and JSSpecialObject to the beginning of
the JSObject range. This seems like the least-brittle way to establish
ranges that also include JSProxy (and these ranges are verified with
static assertions in instance-type.h).
- Renamed @instanceTypeValue to @apiExposedInstanceTypeValue.
- Renamed @instanceTypeFlags to @reserveBitsInInstanceType.
This change introduces the new annotations and adds the ability for
Torque to assign instance types that satisfy those annotations. Torque
now emits two new macros:
- TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the
InstanceType enumeration
- TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String
parts of INSTANCE_TYPE_LIST
The design document mentions a couple of other macro lists that could
easily be replaced, but I'd like to defer those to a subsequent checkin
because this one is already pretty large.

In preparation for allowing Torque to generate the list of instance
types, I'd like to make the rules a bit more consistent for how instance
types are spelled. This CL is my proposal for a system where every
non-String instance type name is exactly equal to calling
CapifyStringWithUnderscores on the corresponding class name and
appending "_TYPE".
This change is almost all find&replace; the only manual changes are in:
- src/objects/instance-type.h
- src/torque/utils.cc
- tools/gen-postmortem-metadata.py
This change is in response to the review comment

This adds a fake toolchain for pointer compression, used for
correctness fuzzing. The toolchain enables us to have an extra build
with inverse pointer-compression defaults side-by-side.
The extra build is used similarly to existing x64/x86 comparisons,
except that we now compare builds with different compile-time flags.
