e26102ac24 Suppress GC stress failure for a test that asserts code being optimized. 
The reason is that GC stress causes additional deopts that the test
originally did not foresee.

8313c523b3 Optimize Map/Set.prototype.forEach 
Instead of using an iterator result object and an entries array
(for Map) we introduce a new runtime function that uses an array
as an out param.

On the Map ForEach perf test this leads to a 2.5x performance
improvement. On the overall Map and Set tests this leads to a 18%
and 13% improvement respectively.

The test expects a function not to deopt. However GC stress causes
the code to be marked for deopt for a reason we are not testing against.

3247a71c78 Do not unnecessarily expose execution state in debug event data. 
When we fire a debug event, we create duplicate execution state objects,
one as argument for the debug event listener, one as property on the
debug event data object. The latter is never used by chrome.

7b7bb25a24 Support external startup data in V8. 
[Re-retry of r21696 and r21739]

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

The case:
v8::TryCatch try_catch;
CompileRun(try { CEvaluate('throw 1;'); } finally {});
CHECK(try_catch.HasCaught());
CHECK(!try_catch.Message().IsEmpty());

CEvaluate is native call. Last check is not passed without patch. Patch contains test TryCatchFinallyStoresMessageUsingTryCatchHandler with more details.

ba9f391bc0 Support external startup data in V8. 
[Retry of crrev.com/293993021, which caused problems with 'ninja all' in Chromium. First patch set if a clean apply
of crrev.com/293993021. Subsequent sets are the actual fix
for that issue.]

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

97c962c255 Add support for extended constant pool arrays. 
This CL adds support for ConstantPoolArrays which contain an extended section.
This will be used to enable larger constant pools than can be addressed by a
single ldr with immediate offset instruction (which has a limit of a 4KB range).
Extended constant pools will have a small section, which is addressable via a
single ldr instruction, and an extended section, which will require a multi-
instruction sequence to load from.

Currently, no code uses the extended ConstantPoolArray's - this change will
be made in a followup CL.

A number of changes are made to the ConstantPoolArray object in order to
support this:
  - Small section layout is now entirely defined by the small layout bitmaps.
  - The ConstantPoolArray no longer extends FixedArrayBase since the length
    field is not useful for extended layouts.
  - Enums are used to represent the type of an entry and the layout section.
  - An iterator can be used to iterate through all elements of a given type.
  - A number of tests were added for these features.

60a71d8a8c Remove PROHIBITS_OVERWRITING as it is subsumed by non-configurable properties. 
v8::DontDelete is set for Unforgeable properties, so just not setting PROHIBITS_OVERWRITING should be enough.

The secondary "feature" of not allowing accessors to be installed in extending objects is incorrect and confusing, given that it only applies to accessors but not to regular properties:
Object.defineProperty({__proto__:window}, "location", { value: 10 })
works where
Object.defineProperty({__proto__:window}, "location", { get: function() {} })
doesn't work.

The original patch which ensured that Object.observe did allocations in the correct context regressed performance about 12%. This patch gets back most of that (about 11%) by simply returning the correct function which is then directly callable from JS, rather than by making the call from the runtime function. A side-effect is that their implementation is shorter.

20eeff9ae4 Allow microtasks to throw exceptions and handle them gracefully 
If the embedder calls V8::TerminateExecution while we're running microtasks, bail out
and clear any pending microtasks.

All other exceptions are simply swallowed. No current Blink or V8 microtasks throw, this
just ensures something sane happens if another embedder decides to pass a throwing
microtask (or if ours unexpectedly throw due to, e.g., stack exhaustion).

7ac892c8bd Establish distributivity for type union & intersection 
This requires introducing proper bounds on all leaf types, so that intersection between bitsets and these types can be accurately represented. Extending a union also becomes more involved.

(On the upside, the modified union/intersect algorithm would now allow support for proper variance for function types.)

Not sure if it is worth landing this. Distributivity isn't really a crucial property for our use cases. It seems fine if intersection is slightly lossy.

3d0bf69cd8 Attempt no. 3 to fix Heap::IsHeapIterable and HeapIterator. 
Now we remember new space's top pointer after the last GC to find out if there was a new space allocation since the last GC.

Unfortunately, this not completely safe - the debugger has a callback hook (that can call to JS) at the end of the GC epilogue that can in theory allocate and possibly make the heap non-iterable. We can only hope this does not happen.

fired twice for a code object. When the event was processed for the first
time it seized the no-fp-ranges from code object, so the second event

As a result when a cpu profile sample falls into the region it missed the

70c3a714a1 ES6 Map/Set iterators/forEach improvements 
This changes how Map/Set interacts with its iterators. When the
underlying table is rehashed or cleared, we create a new table (like
before) but we add a reference from the old table to the new table. We
also add an array describing how to transition the iterator from the
old table to the new table.

When Next is called on the iterator it checks if there is a newer table
that it should transition to. If there is, it updates the index based
on the previously recorded changes and finally changes itself to point
at the new table.

With these changes Map/Set no longer keeps the iterators alive. Also,
as before, the iterators keep the underlying table(s) alive but not the
actual Map/Set.

This avoids the appearence of a leak due to storing a JSObject
as the microtask_state in the strong root list, and allows callers
to call Isolate::RunMicrotasks() without having any v8::Context
available (as at least Blink has interest in doing).

The queue is now a strong root, represented as a FixedArray of JSFunctions
(or empty_fixed_array, if it's empty); it doubles in size when it needs to grow.
The number of elements in the queue is stored in Isolate::pending_microtask_count().

 - CpuFeatures are consolidated into the platform-independent assembler.h
   as much as possible.
 - FLAG_enable_<feature> will only be checked at probing time (already the
   case for ARM).
 - The serializer state is cached by the MacroAssembler.
 - PlatformFeatureScope is no longer necessary.

e876dab9ad ARM64: Fix and improve MacroAssembler::Printf. 
- W-sized values passed to Printf are now handled correctly by the
    simulator. In AAPCS64, int32_t and int64_t are passed in the same
    way, so this didn't affect non-simulator builds.
  - Since Printf now records the type and size of each argument, it is
    possible to mix argument types.
  - It is now possible to print the stack pointer. There is only one
    remaining restriction: The `csp` register cannot be printed unless
    it is the current stack pointer. This is because it is modified by
    BumpSystemStackPointer when the caller-saved registers are
    preserved.

Even although the Arm64 specification specifies that csp
only needs to be aligned to 16 bytes if it is dereferenced, some
implementations show poor performance.

Also makes the following change:
 - Enable CPU support for arm64 to enable probing of cpu implementer and cpu part.
 - Add ALWAYS_ALIGN_CSP CpuFeature for Arm64 and set it based on runtime probing of the cpu imp
 - Rename PrepareForPush and PrepareForPop to PushPreamble and PopPostamble and move PopPostabl
