This is the V8 equivalent to https://crrev.com/2779193002 and must be landed
before //build/secondary/{gtest,gmock} are removed from Chromium. This started
out as https://crrev.com/2847693002
The changes in tools/ were authored by yangguo@chromium.org and
initially shared in http://crrev.com/2849783003.
GoogleTest (gtest) and GoogleMock (gmock) are now hosted into the same
googletest repository. In order to cope with this, the googletest
repository is now sourced at third_party/googletest.
The file/directory layout of Google Test is not yet considered stable.
To minimize disruption while Google Test stabilizes, Chromium code will
be insulated from third_party/googletest.
* testing/gtest/include/gtest/ and testing/gmock/include/gmock have
been populated with headers that forward into the appropriate
locations of third_party/googletest
* testing/BUILD.gn has been populated with the targets
//testing/gtest(:gtest_main) and //testing/gmock(:gmock_main),
which depend on the appropriate //third_party/googletest targets.
All Chromium code should keep depending on the targets and
headers in testing/{gtest,gmock} for now.

Previously we used a FixedArray for the FeedbackMetadata, packing bits
of information into Smi fields. On 64-bit platforms, we waste at least
half of the available memory by using the Smi representation.
Given that this is just raw data (no pointers), we can just use a new
type that uses the existing packing scheme to store the data in int32
format instead.
This CL changes FeedbackMetadata to a new subclass of HeapObject. This
is to reduce the API surface exposed, in comparison to extending/using
a more general purpose data structure like ByteArray, which is also just
raw data.
FeedbackMetadata only exposes general purpose methods for accessing
slots, but hides the implementation detail of packing bits into int32
fields.
This CL also introduces a sentinal EmptyFeedbackMetadata, because there
are ~750 empty FeedbackMetadata objects when running an empty program in
V8. These are probably for builtins.

This changes the JSArrayIterator to always have only a single instance
type, instead of the zoo of instance types that we had before, and
which became less useful with the specification update to when "next"
is loaded from the iterator now. This greatly simplifies the baseline
implementation of the array iterator, which now only looks at the
iterated object during %ArrayIteratorPrototype%.next invocations.
In TurboFan we introduce a new JSCreateArrayIterator operator, that
holds the IterationKind and get's the iterated object as input. When
optimizing %ArrayIteratorPrototype%.next in the JSCallReducer, we
check whether the receiver is a JSCreateArrayIterator, and if so,
we try to infer maps for the iterated object from there. If we find
any, we speculatively assume that these won't have changed during
iteration (as we did before with the previous approach), and generate
fast code for both JSArray and JSTypedArray iteration.
Drive-by-fix: Drop the fast_array_iteration protector, it's not
necessary anymore since we have the deoptimization guard bit in
the JSCallReducer now.
This addresses the performance cliff noticed in webpack 4. The minimal
repro on the tracking bug goes from
console.timeEnd: mono, 124.773000
console.timeEnd: poly, 670.353000
to
console.timeEnd: mono, 118.709000
console.timeEnd: poly, 141.393000
so that's a 4.7x improvement.
Also make presubmit happy by adding the missing #undef's.

This enables the v8_enable_embedded_builtins gn flag on non-ia32 builds
and adds a new --stress-off-heap-code test mode to fyi bots.
v8_enable_embedded_builtins=true changes accesses to constants and
external references to go through the root list in builtins code.
--stress-off-heap-code copies builtins code off-heap on isolate
creation.
A few drive-by-fixes:
- ensure that we actually inspect the correct builtin during
isolate-independence testing.
- relax tests to decrease maintenance (now we only fail if a builtin
should be isolate-independent but isn't).
- switch to a different off-heap-trampoline register on arm due to
conflicts with custom stub linkages.

This is preparatory cleanup work for eventually tracking the functions
(rather than concrete closures) in the CALL_IC, also for builtins like
the default PromiseCapability [[Resolve]] and [[Reject]] functions. It
adds a new FeedbackCell type, which is used by JSFunctions consistently
now to reference the feedback vector (or undefined if not the function
is not compiled yet or is a native/asm.js function).
This also changes the calling convention for FastNewClosure builtin and
the JSCreateClosure operator in TurboFan to carry the FeedbackCell here
instead of the parent FeedbackVector and the slot index. In addition we
eliminate the now unused %InterpreterNewClosure runtime function.

This is a partial revert of:
https://crrev.com/c/890938 and https://crrev.com/c/893982
Before this CL, the test runner blocked on ongoing tests in order to
process their results after an internal timeout. However, the logic
required for this feature was overly complicated and prevented an
acceptable implementation for fast aborts. Furthermore, also the fuzzers
suffered from timeouts on swarming due to hanging tests.
Instead, we now abort immediately on internal timeout (used on
fuzzers), SIGINT (Ctrl-C) and SIGTERM. Ongoing tests are immediately
terminated and their results are disregarded. On SIGTERM and SIGINT,
we return with non-zero exit codes, and zero on internal timeout.
This will also properly return json output, when the external hard
timeout is reached on swarming (causes SIGTERM).

This adds a new isolate wide Promise#then protector, which guards the
"then" lookup for all JSPromise instances whose [[Prototype]] is the
initial %PromisePrototype%. Thus arbitrary mutations to the
Promise.prototype (i.e. monkey-patching other methods or installing
new functions) no longer sent you down the slow-path. Use this protector
in Promise.prototype.catch and in Promise.resolve.
Drive-by-fix: Restructure the resolve logic a bit and avoid the
expensive and large SameValue check, which can be turned into a simple
reference equal, as the promise in there is known to be a JSPromise
anyways.

This implements the ideas outlined in the section "Microtask queue"
of the exploration document "Promise and async/await performance" (at
https://goo.gl/WHRar2), except that the microtask queue stays a linear
FixedArray for now, to avoid running into trouble with the parallel
scavenger. This way we can already save a significant amount of
allocations, thereby reducing the GC frequency quite a bit.
All items on the microtask queue are now proper structs that subclass
Microtask, i.e. we also wrap JSFunction and MicrotaskCallback jobs
into structs. We also consistently remember the context for every
microtask (except for MicrotaskCallback where we don't have a
context), and execute it later in exactly that context (as required
by the spec anyways for the Promise related jobs). Particularly
interesting is the PromiseReactionJobTask and its subclasses, since
they are designed to have the same size as the PromiseReaction. When
we resolve a JSPromise we just take the existing PromiseReaction
instances and morph them into PromiseFulfillReactionJobTask or
PromiseRejectReactionJobTask (depending whether you "Fulfill" or
"Reject"). That way the JSPromise class is now only 6 words instead
of 10 words.
Also the PromiseReaction and the reaction tasks can either carry a
JSPromise (for the fast native case) or a PromiseCapability (for the
generic case), which means we don't always pay the overhead of having
to also remember the "deferred resolve" and "deferred reject" handlers
that are only relevant for the generic case anyways.
It also fixes a spec violation where we called "then" before we actually
enqueued the PromiseResolveThenableJob, which is observably wrong.
Calling it later has the advantage that it should be fairly
straight-forward now to completely avoid it for native Promise
instances.
This seems to save around 10-20% on the various Promise benchmarks and
micro-benchmarks. We expect to gain even more as we're now able to
inline various operations into TurboFan optimized code easily.

a native JSPromise instance and initializes it to pending state.
In addition to that we introduce a new PromiseHookProtector, which
get's invalidated the first time someone enables the debugger or
installs a PromiseHook (via async_hooks for example). As long as
the protector is intact we lower AsyncFunctionPromiseCreate to
JSCreatePromise and AsyncFunctionPromiseRelease to a no-op in
optimized code.
This yields a speedup of roughly 33% on the benchmark mentioned

Since test processors create tests dynamically we cannot simply
count how many tests will be run. Instead we count only base tests

This adds a reduced version of bot_default with only d8-based test suites.
Those can be used for gc stress testing, fuzzing and predictable mode.
This also adds a missing explicit build rule for the debugger test suite.
It's working as it's part of the isolate file, but incremental
re-isolation might break on code changes.
Running the tests is still commented out to allow the infra-side to
land. Afterwards, we'll activate the extra testing as a V8 CL
commenting the lines back in.

We collect instance type statistics in FatalProcessOutOfMemory into an
array, which is allocated to the max instance type value. While we want
to leave space to ensure new instance types do not affect constants in
the API, we can be more frugal.
We currently serialize 350 maps into the startup/context snapshot. Even
if we assign a distinct instance type to each of these maps, we would
still have more than enough to spare with this change.

Once this CL lands and is included in Node.js, we can
- run `tools/node/fetch_deps.py <v8_path>` to fetch necessary deps.
- run `tools/node/build_gn.py <build mode> <v8_path> <out_dir>` to build.
- use new v8_monolith target in v8.gyp to call build_gn.py.

to fail in the mozilla test suite, which pass in predictable mode.
Now, negative tests are simply not supported.

- All `testcase` variables renamed to `test` to not conflict with
a module name.
- No more two statements in the same line.
