9a9ba762bf Revert "Use list of invalidated objects for old-to-new refs"
This reverts commit 60843b426b.

Reason for revert: TSAN detected issue between Scavenge workers.
One task could invoke RefillFreeList(), while the other task iterates the remembered set of a swept page.

60843b426b Use list of invalidated objects for old-to-new refs
Instead of inserting "deletion" entries into the store buffer, keep a
list of invalidated objects to filter out invalid old-to-new slots.

The first CL https://crrev.com/c/1704109 got reverted because both the
sweeper and the main task were modifying the invalidated slots data
structure concurrently. This CL changes this, such that the sweeper
only modifies the invalidated slots during the final atomic pause when
the main thread is not running. The sweeper does not need to clean this
data structure after the pause, since the "update pointers" phase
already removed all invalidated slots.

The second CL https://crrev.com/c/1733081 got reverted because the
sweeper might find more free space than the full GC before it. If an
object shrinks after the pause but before the sweep, the invalidated
object might span free memory and potentially new allocated objects.
Therefore shrink invalidated objects when processing swept pages on
the main thread. Also clean recorded slots in the gap.

3bd4ac9d20 [Parsing] Create canononical ScopeInfos in the read-only space.
Create canonical ScopeInfos for the global this binding and empty function in
the read only space, rather than creating them during bootstrapping for each
native context. This saves some memory, and also means we don't need to access
the native context to get the global this binding in when deserializing a
scope info, which is important since parsing should be native context independent.

79b00555ea [torque] introduce JSAny type for user-accessible JavaScript values
This CL introduces a JSAny type for user-exposed JavaScript values and
a few new types to define it. Especially, it splits Symbol into
PrivateSymbol (not exposed) and PublicSymbol (JavaScript exposed
symbols).

The change is mostly mechanical, but a few things are interesting:
- PropertyKey and JSPrimitive were designed to coincide with the spec
  notions of IsPropertyKey() and primitive value, respectively.
- Since Name is an open type, we define AnyName to be the known
  subtypes of Name. This is not too elegant, but by using AnyName
  instead of Name, typeswitch can properly conclude something if a
  subtype of Name is excluded.

Small drive-by changes, which were necessary:
- Allow subtyping on label parameters.
- Fix the formatting of typeswitch, it was broken with union types
  in case types.

e2f98ec22c Use list of invalidated objects for old-to-new refs
Instead of inserting "deletion" entries into the store buffer, keep
a list of invalidated objects to filter out invalid old-to-new slots.

The first CL https://crrev.com/c/1704109 got reverted because both the sweeper and the main task were modifying the invalidated slots data structure concurrently. This CL changes this, such that the sweeper only modifies the invalidated slots during the final atomic pause when the main thread is not running. The sweeper does not need to clean this data structure after the pause, since the "update pointers" phase already removed all invalidated slots.

0921e8f28b Reland "Add postmortem debugging helper library"
This is a reland of 517ab73fd7

Updates since original: now compressed pointers passed to the function
GetObjectProperties are required to be sign-extended. Previously, the
function allowed zero-extended values, but that led to ambiguity on
pointers like 0x88044919: is it compressed or is the heap range actually
centered on 0x100000000?

Original change's description:
> Add postmortem debugging helper library
>
> This change begins to implement the functionality described in
> https://docs.google.com/document/d/1evHnb1uLlSbvHAAsmOXyc25x3uh1DjgNa8u1RHvwVhk/edit#
> for investigating V8 state in crash dumps.
>
> This change adds a new library, v8_debug_helper, for providing platform-
> agnostic assistance with postmortem debugging. This library can be used
> by extensions built for debuggers such as WinDbg or lldb. Its public API
> is described by debug-helper.h; currently the only method it exposes is
> GetObjectProperties, but we'd like to add more functionality over time.
> The API surface is restricted to plain C-style structs and pointers, so
> that it's easy to link from a debugger extension built with a different
> toolchain.
>
> This change also adds a new cctest file to exercise some basic
> interaction with the new library.
>
> The API function GetObjectProperties takes an object pointer (which
> could be compressed, or weak, or a SMI), and returns a string
> description of the object and a list of properties the object contains.
> For now, the list of properties is entirely based on Torque object
> definitions, but we expect to add custom properties in future updates so
> that it can be easier to make sense of complex data structures such as
> dictionaries.
>
> GetObjectProperties does several things that are intended to generate
> somewhat useful results even in cases where memory may be corrupt or
> unavailable:
> - The caller may optionally provide a type string which will be used if
>   the memory for the object's Map is inaccessible.
> - All object pointers are compared against the list of known objects
>   generated by mkgrokdump. The caller may optionally provide the
>   pointers for the first pages of various heap spaces, to avoid spurious
>   matches. If those pointers are not provided, then any matches are
>   prefixed with "maybe" in the resulting description string, such as
>   "maybe UndefinedValue (0x4288000341 <Oddball>)".

743ce7726d [WeakRefs] Make cleanup callback run as a task
Previously, this was run as a microtask and this CL changes it to run
as a separate task as mandated by the current WeakRef spec.

This CL also introduces a FinalizationGroup type to the V8 API
representing the JSFinalizationGroup. This has a `Cleanup`
function that runs the cleanup callback associated with it.

SetHostCleanupFinalizationGroupCallback is added to set
the embedder defined HostCleanupFinalizationGroupCallback.

ClearKeptObject is exposed on the v8::Isolate to reset the strongly
held set of objects.

The general workflow is the following:

(a) When the GC notices that a given finalization group has dirty
    cells, it calls HostCleanupFinalizationGroupCallback with the given
    finalization group.

(b) As part of HostCleanupFinalizationGroupCallback, the embedder
    enqueues a task that at some point later calls
    FinalizationGroup::Cleanup.

(c) At some point in the future, FinalizationGroup::Cleanup is called,
    which runs the cleanup callback of the finalization group.

This patch also includes d8 changes to use these new APIs. Currently,
d8 cycles through the enqueued finalization groups after a synchronous
turn (and it's microtask checkpoint) and runs the cleanup callbacks.

517ab73fd7 Add postmortem debugging helper library
This change begins to implement the functionality described in
https://docs.google.com/document/d/1evHnb1uLlSbvHAAsmOXyc25x3uh1DjgNa8u1RHvwVhk/edit#
for investigating V8 state in crash dumps.

This change adds a new library, v8_debug_helper, for providing platform-
agnostic assistance with postmortem debugging. This library can be used
by extensions built for debuggers such as WinDbg or lldb. Its public API
is described by debug-helper.h; currently the only method it exposes is
GetObjectProperties, but we'd like to add more functionality over time.
The API surface is restricted to plain C-style structs and pointers, so
that it's easy to link from a debugger extension built with a different
toolchain.

This change also adds a new cctest file to exercise some basic
interaction with the new library.

The API function GetObjectProperties takes an object pointer (which
could be compressed, or weak, or a SMI), and returns a string
description of the object and a list of properties the object contains.
For now, the list of properties is entirely based on Torque object
definitions, but we expect to add custom properties in future updates so
that it can be easier to make sense of complex data structures such as
dictionaries.

GetObjectProperties does several things that are intended to generate
somewhat useful results even in cases where memory may be corrupt or
unavailable:
- The caller may optionally provide a type string which will be used if
  the memory for the object's Map is inaccessible.
- All object pointers are compared against the list of known objects
  generated by mkgrokdump. The caller may optionally provide the
  pointers for the first pages of various heap spaces, to avoid spurious
  matches. If those pointers are not provided, then any matches are
  prefixed with "maybe" in the resulting description string, such as
  "maybe UndefinedValue (0x4288000341 <Oddball>)".

cd34523b9b [wasm][tests] Add proposal tests to the wasm spec tests
With this CL we add proposal tests to the wasm-spec-tests. For this I
extended the update-wasm-spec-tests.sh script. Additionally to
generating the spec tests it does the following:

For each proposal it identifies those tests that are different to the
spec tests, and then copies those tests also to the wasm-spec-tests
directory.

Additionally I adjusted the test runner of the wasm spec test to
run the proposal tests with the correct flags.

perfrunner returns a failure if the build timeouts at any point even if it's
successful after retries. It tries to surface up the timeout issue. Due to this,
some bots stay red consistently, and confuses the sheriffs.

This CL masks the timeouts if the suite succeeds in the end.

14274bb16a [torque] Use @generateCppClass in some simple cases
This change is mostly mechanical, but it's worth mentioning a few
slightly interesting cases:
- A couple of field definitions didn't match the signedness of their
  corresponding accessors.
- The generated accessors for Smi data use Smi values directly, but
  usually we want C++ accessors to use ints instead. I added a macro
  that hides the generated Smi accessors and exposes int accessors,
  but we might consider generating int accessors directly.
- The data held in some fields is described in comments next to the
  accessor definition for those fields. With automatically generated
  accessors, those comments need a new home. In this change I put them
  in the Torque object definition, but I'm open to other suggestions.
- gen-postmortem-metadata couldn't find updated class definitions after
  they got split across multiple lines, so I changed its matching
  logic. (Ideally debug-support.cc should be a Torque compiler output
  rather than something that involves parsing C++ with regexes, but
  this makes it correctly report subclass relationships for now.)
- The end offsets generated by Torque were off by one from the values
  that would be generated by DEFINE_FIELD_OFFSET_CONSTANTS.

b086cb7b9a Check that function was prepared before optimizing using manually
With lazy feedback allocation and bytecode flushing we need to call
%PrepareFunctionForOptimize before we call %OptimizeFunctionOnNextCall/
%OptimizeOsr. This cl:
1. Adds an additional state in pending optimized table to check if the
optimization was triggered manually.
2. Changes the compilation pipeline to delete the entry from pending
optimized table only if the optimization was triggered through
%OptimizeFunctionOnNextCall / %OptimizeOsr.
3. Adds a check to enforce %PrepareFunctionForOptimize was called.
4. Adds a new run-time flag to only check in the d8 test runner. We
don't want this check enabled in other cases like clusterfuzz that doesn't
ensure %PrepareFunctionForOptimize is called.

fa2bed3f74 [regexp] Move the RegExpSpeciesProtector to the native context
Prior to this CL, it was possible to pollute another context's
fast/slow-path state for RegExp builtins due to the species protector
being per-isolate rather than per-context. Among other things, this
means that iframes can slow down the main site, and slowdowns persist
across page reloads and navigation within the same tab.

This CL thus moves the RegExpSpeciesProtector to the native context.

The same should be done for all other protectors in the future.

1db33e5fff [browser-stories] gate features behind {experimental} flag
Performance infra recipes use callstats.py to run web page replays. Split (v8,
infa, perf-infra) repositories make experimenting with callstats.py hard.

This CL creates feature gating for simplifying performance infra experiments.

8e11cc395a Enable cpplint 'runtime/references' warning
Cpplint usually checks for non-const reference arguments. They are
forbidden in the style guide, and v8 does not explicitly make an
exception here.
This CL re-enables that warning, and fixes all current violations by
adding an explicit "NOLINT(runtime/references)" comment. In follow-up
CLs, we should aim to remove as many of them as possible.

2fe2a08b0c [wasm] Introduce WasmIndirectFunctionTable
This is the first of three CLs which refactors indirect function calls
through tables with index > 0 to work without runtime calls.

The first CL introduces the WasmIndirectFunctionTable heap object. For
a table of type anyfunc within a WebAssembly instance,
WasmIndirectFunctionTable stores the size, the signature id's, the
call targets, and the reference parameters for that table. I used the
names that are already used for the matching fields of the
WasmInstanceObject.

The second CL expands the IndirectFunctionTableEntry to work also on
WasmIndirectFunctionTable objects. All changes to a function table go
through this class.

The third CL introduces uses of the WasmIndirectFunctionTable. In this
CL I change the code generation in TurboFan to replace runime calls with
direct accesses to the new WasmIndirectFunctionTable. Additionally I
extended the initialization of WasmIndirectFunctionTable, and also
implement Table.grow.
