The two refactorings are somewhat orthogonal, but intersect at the
class and instance type list generation, which is why it's easier to
put them in one CL.
For the removal of HasIndexedField, the removal is motivated by the
fact that is no longer necessary, and that using a flag to store this
kind of information is hacky.
For the class list changes, this is a cleanup in that we no longer
generate third-order macros, but instead normal macro lists.
There is a functional change and bug-fix in that we no longer include
abstract classes in lists that refer to instance types or maps. It's
still somewhat broken though, so I can't test abstract internal classes
yet, though. Coming in a follow-up CL.

Bill kindly pointed out to me that v8windbg was not handling bit_field2
correctly. The issue was that the constexpr type for ElementsKind was,
somewhat unsurprisingly, "ElementsKind", but v8windbg expected a fully-
qualified type name like "v8::internal::ElementsKind". This change
addresses the problem in two ways:
1. Update v8windbg's type resolution logic to resolve type names as if
they were used in the v8::internal namespace. This makes it more
consistent with how those type names are used in other generated
Torque code, reducing surprises and the number of times we have to
write `v8::internal::` in .tq files.
2. Add compile-time verification that any constexpr type name used as a
string in class-debug-readers-tq.cc can also resolve as a type name.

* Add a new "@generateBodyDescriptor" annotation that causes Torque to

* Fully automate C++ macro machinery so that adding non-extern Torque

* Make handling of @export a true annotation, allowing the modifier to

* Add functionality such that classes with the @export annotation are
available to be used from C++. Field accessors for exported classes
are public and factory methods are generated to create instances of
the objects from C++.
* Change the Torque compiler such that Non-exported classes implicitly
have the @generateBodyDescriptor annotation added and causes both
verifiers and printers to be generated.
* Switch non-extern Torque classes from using existing Struct-based
machinery to being first-class classes that support more existing
Torque class features.

This allows CoverageInfo to be distinguished from other kinds of
FixedArray at runtime. I also updated it to use untagged data since it
only stores ints, since that seems like the generally right thing to do
(even though I doubt anybody allocates enough of these to notice the
reduced GC work).
Related Torque changes:
- Allow structs containing untagged data to be used as class fields.
This requires classifying them into the tagged or untagged sections of
the class layout, and checking that their alignment requirements are
met when stored in a packed array.
- Generate a struct containing struct field offsets, so we can ensure
that the layouts defined in Torque and C++ code match. Of course it
would be nice to generate a lot more (indexed accessors, synchronized
accessors, GC visitors, etc.), but we can't do it all at once.

These both have to do with extremely large numbers, so it's unlikely to cause a problem in practice. Still, correctness.
First, encoding `-2147483648` in VLQ returns the value `"B"`. When decoding, we get the value `1` after reading the base64. We then check if the first bit is set (it is) to see if we should negate it, then we shift all bits right once. Now, `value` will be `0` and `negate` will be `true`. So, we'd return `-0`. Which is a bug! `-0` isn't `-2147483648`, and we've broken a round trip.
Second, encoding any number with the 31st bit set, we'd return the opposite sign. Let's use `1073741824`. Encoding, we get `"ggggggC"`. When decoding, we get the value `-2147483648` after reading the base64. Notice, it's already negative (the 32nd bit is set, because the 31st was set and we shifted everything left once). We'd then check the first bit (it's not) and shift right. But we used `>>`, which does not shift the sign bit. We actually wanted `>>>`, which will. Because of that bug, we get back `-1073741824` instead of the positive `1073741824`. It's even worse if the 32nd and 31st bits are set, `-1610612736` becomes `536870912` after a round trip.

This adds a new API function that can be customized by the embedder
by providing a delegate that defines contexts to be measured and
reports the results to JS.
A memory measurement request is carried out as follows:
1) MeasureMemory(delegate) invocation enqueues a new request in
MemoryMeasurement::received_ and schedules a delayed GC task.
2) At the start of the next GC (that is triggered either by the
GC schedule or by the delayed task) each request in received_
moves to processing_. Per-context marking worklists are created
for each native context that was selected by the delegates
(using the ShouldMeasure predicate).
3) At the end of the GC the sizes of the native contexts are
recorded for each request in processing_. The requests move
to the done_ list and result reporting task is scheduled.
4) When the result reporting task runs it invokes the
MeasurementComplete function of each delegate in done_.

When an overall timeout is reached, swarming sends a SIGTERM to
terminate the test runner. The test runner has a signal handler on the
main process to terminate all workers gracefully.
Additionally, every worker process installs a signal handler for
terminating ongoing tests wrapped by command.Command.
Also, command.Command is used on the main process to list tests for
cctest and gtest executables, which led to overriding the test runner's
main signal handler.
This CL disables using signal handlers in commands by default and only
explicitly enables it in safe source locations.

This change moves the definitions of the bitfield flags used by Symbol
and Map to Torque. Symbol could directly follow the pattern established
by SharedFunctionInfo, but Map required some other changes:
- Until now, Torque bitfield definitions have required unsigned types. I
thought that this would be the least-surprising behavior, since we
never sign-extend when decoding bitfield values. However, I believe
that the amount of churn involved in making ElementsKind be unsigned
outweighs the benefit we were getting from this restriction (and
similar difficulties are likely to arise in converting other bitfield
structs to Torque), so this CL updates Torque to allow signed bitfield
values.
- If we try to make Map extend from all of the generated classes that
define its flags, we end up with class sizing problems because some
compilers only apply empty base class optimization to the first in a
row of empty base classes. We could work around this issue by
generating macros instead of classes, but I took this as an
opportunity for a minor clean-up instead: rather than having bitfield
definitions for several different bitfield structs all jumbled
together in Map, they can be split up. I think this makes the code a
little easier to follow, but if others disagree I'm happy to implement
macro generation instead.

When V8 throws an uncaught exception, we store a JSMessageObject
with a stack trace and source positions on the isolate itself.
The JSMessageObject can be retrieved by a TryCatch scope
and is used by the inspector to provide additional information to the DevTools
frontend (besides the exception).
Introducing top-level await for REPL mode causes all thrown exceptions
to be turned into a rejected promise. The implicit catch block that does this
conversion clears the JSMessageObject from the isolate as to not leak memory.
This CL preserves the JSMessageObject when the debugger is active and stores
the JSMessageObject on the rejected promise itself. The inspector is changed
to retrieve the JSMessageObject in the existing catch handler and pass the
information along to the frontend.
Drive-by: This CL removes a inspector test that made assumptions when a promise
is cleaned up by the GC. These assumptions no longer hold since we hold on to
the promise longer.

This is a reland of 5bddc0e142
The original CL was speculatively reverted as it was suspected to
cause failures on the non-determinism bot. This was ultimately
confirmed to not be the case, so this CL is safe to reland as-is.
Original change's description:
> Implement top-level await for REPL mode
>
> Design doc: bit.ly/v8-repl-mode
>
> This CL allows the usage of 'await' without wrapping code in an async
> function when using REPL mode in global evaluate. REPL mode evaluate
> is changed to *always* return a Promise. The resolve value of the
> promise is the completion value of the REPL script.
>
> The implementation is based on two existing mechanisms:
> - Similar to async functions, the content of a REPL script is
> enclosed in a synthetic 'try' block. Any thrown error
> is used to reject the Promise of the REPL script.
>
> - The content of the synthetic 'try' block is also re-written the
> same way a normal script is. This is, artificial assignments to
> a ".result" variable are inserted to simulate a completion
> value. The difference for REPL scripts is, that ".result" is
> used to resolve the Promise of the REPL script.
>
> - ".result" is not returned directly but wrapped in an object
> literal: "{ .repl_result: .result}". This is done to prevent
> resolved promises from being chained and resolved prematurely:
>
> > Promse.resolve(42);
>
> should evaluate to a promise, not 42.

Design doc: bit.ly/v8-repl-mode
This CL allows the usage of 'await' without wrapping code in an async
function when using REPL mode in global evaluate. REPL mode evaluate
is changed to *always* return a Promise. The resolve value of the
promise is the completion value of the REPL script.
The implementation is based on two existing mechanisms:
- Similar to async functions, the content of a REPL script is
enclosed in a synthetic 'try' block. Any thrown error
is used to reject the Promise of the REPL script.
- The content of the synthetic 'try' block is also re-written the
same way a normal script is. This is, artificial assignments to
a ".result" variable are inserted to simulate a completion
value. The difference for REPL scripts is, that ".result" is
used to resolve the Promise of the REPL script.
- ".result" is not returned directly but wrapped in an object
literal: "{ .repl_result: .result}". This is done to prevent
resolved promises from being chained and resolved prematurely:

should evaluate to a promise, not 42.

This cl: https://chromium-review.googlesource.com/c/v8/v8/+/1924439 has
renamed the optimize passed happening on the backgroudn to
OptimizeBackground instead of OptimizeConcurrent or RecompileConcurrent.
Concurrent optimization has main thread phases so using
OptimizeConcurrent for background computations only was a bit confusing.

Until now, the in-object properties on JSObject have been invisible to
tools using the postmortem debugging library. With this change, those
tools will get enough information to show a flat list of property
values. This is still less powerful than the runtime printers, which can
show the corresponding key for each value, but it's a big step up from
manually inspecting memory.
This change basically requires a reimplementation of
Map::GetInObjectProperties for postmortem debugging. I'm not
enthusiastic about duplicating this logic, but it's pretty small and I
don't see any good alternatives.
As a drive-by cleanup, I moved some inline string literals into a batch
of constexpr char arrays.

This CL ensures we care only about our internal pointer types and not
about raw C++ pointers, because normally special care is taken when
storing raw pointers to the managed heap. Furthermore, checking for raw

This change defines a way that v8_debug_helper can describe object
fields which are packed structs, and uses it for the "descriptors" field
in DescriptorArray.
In more detail:
- debug-helper.h (the public interface for v8_debug_helper) adds a size
and an optional list of struct properties to ObjectProperty.
- debug-helper-internal.h mirrors those changes to the internal class
hierarchy which maintains proper unique_ptr ownership.
- In src/torque/class-debug-reader-generator.cc,
- Some existing logic is moved into smaller functions.
- New logic is added to generate the field list for structs. Example
output is included in a comment above the function
GenerateGetPropsChunkForField.

Since the grace period for stable bisection is over, we now use
the same random number generator throughout the fuzz session which
leads to a wider range of differently chosen flags.
