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
