b922b0dd8a Fix and improve Map::CurrentMapForDeprecatedInternal(). 
Inline relevant bits from Map::FindUpdatedMap() and Map::IsMoreGeneralThan()
into Map::CurrentMapForDeprecatedInternal() to fix issues introduced
with field type tracking, avoid the useless second pass over the transition
tree, and finally make it easier to understand what this method actually
does.

88ca76bce1 Fix CurrentMapForDeprecated() to return MaybeHandle instead of a null handle. 
Also fix TryMigrateInstance() to return bool instead of the parameter or
a null handle.

5ef2c18639 JSObject::DeepCopy and other functions returned an empty handle to 
indicate an exception. All usages but one changed to return
MaybeHandles, and to use macros around the call.

The remaining work is in Compiler::GetUnoptimizedCode(), and when
that is turned into a MaybeHandle, then the macros dealing with
null handle returns can be eliminated.

3308cb5857 ES6: Add support for Map/Set forEach 
This implements MapIterator and SetIterator which matches
the same constructs in the ES6 spec. However, these 2
iterators are not exposed to user code yet. They are only
used internally to implement Map.prototype.forEach and
Set.prototype.forEach.

Each iterator has a reference to the OrderedHashTable where
it directly accesses the hash table's entries.

The OrderedHashTable has a reference to the newest iterator
and each iterator has a reference to the next and previous
iterator, effectively creating a double linked list.

When the OrderedHashTable is mutated (or replaced) all the
iterators are updated.

When the iterator iterates passed the end of the data table
it closes itself. Closed iterators no longer have a
reference to the OrderedHashTable and they are removed from
the double linked list. In the case of Map/Set forEach, we
manually call Close on the iterator in case an exception was
thrown so that the iterator never reached the end.

At this point the OrderedHashTable keeps all the non finished
iterators alive but since the only thing we currently expose
is forEach there are no unfinished iterators outside a forEach
call. Once we expose the iterators to user code we will need
to make the references from the OrderedHashTable to the
iterators weak and have some mechanism to close an iterator
when it is garbage collected.

a1af5a2a2f ES6: Add support for Map/Set forEach 
This implements MapIterator and SetIterator which matches
the same constructs in the ES6 spec. However, these 2
iterators are not exposed to user code yet. They are only
used internally to implement Map.prototype.forEach and
Set.prototype.forEach.

Each iterator has a reference to the OrderedHashTable where
it directly accesses the hash table's entries.

The OrderedHashTable has a reference to the newest iterator
and each iterator has a reference to the next and previous
iterator, effectively creating a double linked list.

When the OrderedHashTable is mutated (or replaced) all the
iterators are updated.

When the iterator iterates passed the end of the data table
it closes itself. Closed iterators no longer have a
reference to the OrderedHashTable and they are removed from
the double linked list. In the case of Map/Set forEach, we
manually call Close on the iterator in case an exception was
thrown so that the iterator never reached the end.

At this point the OrderedHashTable keeps all the non finished
iterators alive but since the only thing we currently expose
is forEach there are no unfinished iterators outside a forEach
call. Once we expose the iterators to user code we will need
to make the references from the OrderedHashTable to the
iterators weak and have some mechanism to close an iterator
when it is garbage collected.

This is an initial step towards tracking the exact types instead of just
the representations of fields. It adds support to track up to one map of
heap object field values, eliminating various map checks on values
loaded from such fields, at the cost of making stores to such fields
slightly more expensive.

Issues with transitioning stores and fast object literals in Crankshaft
fixed.

8aa93f2443 Bugfix: A TransitionArray can disappear during copy. 
During handlification of TransitionArray code, an error was introduced
in TransitionArray::CopyInsert because after creating a copy of a
TransitionArray, it may be that the array disappears during GC
because it is modified during the marking of the owning map.

8e9eebeba1 OrderedHashTable implementation with Set and Map interfaces 
OrderedHashTable is an insertion-ordered HashTable based on
Jason Orendorff's writeup of a data structure attributed to Tyler Close:
https://wiki.mozilla.org/User:Jorend/Deterministic_hash_tables

It is intended as the new backing store for JSSet/JSMap, as ES6 requires
insertion-order-based iteration. Note, however, that in the interest of
keeping the initial check-in small this patch does not yet include any
iteration support.

This change also doesn't yet touch any existing behavior, but in
a branch I've verified that these structures pass the existing
JSSet/JSMap mjsunit tests.

c21cf2d334 Function calls are handled with a LoadIC and a FunctionCallStub. This works well, but we can create a platform to gather custom feedback by inventing a CallIC. CallIC takes a JSFunction as input, maintains UNINIT/MONO/MEGA state in a feedback slot, and engages in limited patching for the most efficient code. 
The change creates a degrade in NBody tests, but a follow-on CL addresses it by using this custom feedback platform to give a 45% improvement.

has been called on Array that's undergoing truncation).

dd28969c1c Continued fix for 351257. Reusing the feedback vector is too complex. 
Attempting to re-use the type feedback vector stored in the
SharedFunctionInfo turns out to be difficult among the various cases.
It will be much easier to do this when deferred type feedback processing
is removed, as is in the works.

Created bug v8:3212 to track re-introducing the optimization of reusing
the type vector on recompile before optimization.

The CL also brings back the type vector on the SharedFunctionInfo.

6115a006fd Bugfix for 349874: we incorrectly believe we saw a growing store 
When we set an out of bounds array index, the index might be so large that
it causes the array to go to dictionary mode. It's better to avoid
"learning" that this was a growing store in that case.

This fix also partially reverts a fix for bug 347543, as this fix is
comprehensive and satisfies that repro case as well (partial revert of
v19591).

b9e0b87a5a Clear optimized code cache in shared function info when code gets deoptimized. 
This adds a pointer to the shared function info into deoptimization data of an optimized code. Whenever the code is deoptimized, it clears the cache in the shared function info.

This fixes the problem when the optimized function dies in new space GC before the code is deoptimized due to code dependency and before the optimized code cache is cleared in old space GC (see mjsunit/regress/regress-343609.js).

This partially reverts r19603 because we need to be able to evict specific code from the optimized code cache.

0d34254f8d Upgrade Symbol implementation to match current ES6 behavior. 
Refresh the implementation of Symbols to catch up with what the
specification now mandates:

* The global Symbol() function manufactures new Symbol values,
  optionally with a string description attached.

* Invoking Symbol() as a constructor will now throw.

* ToString() over Symbol values still throws, and
  Object.prototype.toString() stringifies like before.

* A Symbol value is wrapped in a Symbol object either implicitly if
  it is the receiver, or explicitly done via Object(symbolValue) or
  (new Object(symbolValue).)

* The Symbol.prototype.toString() method no longer throws on Symbol
  wrapper objects (nor Symbol values.) Ditto for Symbol.prototype.valueOf().

* Symbol.prototype.toString() stringifies as "Symbol("<description>"),
  valueOf() returns the wrapper's Symbol value.

* ToPrimitive() over Symbol wrapper objects now throws.

Overall, this provides a stricter separation between Symbol values and
wrapper objects than before, and the explicit fetching out of the
description (nee name) via the "name" property is no longer supported
(by the spec nor the implementation.)

Adjusted existing Symbol test files to fit current, adding some extra
tests for new/changed behavior.

f6d1a4fef1 Allow externalizing strings in old pointer space. 
This is what I think is a better solution to the "external strings in
old pointer space" problem. Basically, it is an issue because GC scans
all fields of objects in old pointer space and if the cached address
of the backing store is unaligned, it looks like a heap object, boom.

The solution here is to use short external strings when we externalize
a string in old pointer space, and when the address is unaligned.
Short external strings don't cache the address, so GC has no issues.

155ef100e9 Fix logic error in assert in IsUndeclaredGlobal() 
Recent changes in IC logic meant that CallStubs no longer use the Contextual bit. IsUndeclaredGlobal() needed to adjust for that.

In fact, now the CL has morphed to remove the notion of storing contextual state in the IC at all, it just becomes some extra ic state of the load ic. This took some adjustment in harmony code to use the global receiver for certain stores.

Now it's clearer that only LoadICs actually record any information about contextual or not.

then we revive the cell by marking it. Otherwise, the cell value is dead, so

e654c88fab Remove flag track-allocation-sites. 
The flag has been on in the build for ~9 months, and we aren't likely to turn it off. The only customer of the flag is a set of tests that want to verify transitioning behavior in isolation. This CL removes the flag and updates those tests to get what they want without the flag.

cd5ea74700 Replace 'operator*' with explicit 'get' method on SmartPointer 
Made operator* return reference to the raw type, not pointer. New method 'get()' should be used when raw pointer is needed.

Also removed useless inline modifier from the SmaprtPointer methods and added const modifier to the methods that don't change smart pointer.

Made ~SmartPointerBase protected to avoid accidental calls of the non-virtual base class's destructor.

e943623b12 Harmony promises 
Based on prototype at

  https://github.com/rossberg-chromium/js-promise

which informed the latest spec draft version at

  https://github.com/domenic/promises-unwrapping/blob/master/README.md

Activated by --harmony-promises.

Feature complete with respect to the draft spec, plus the addition of .when and .deferred methods. Final naming and other possible deviations from the current draft will hopefully be resolved soon after the next TC39 meeting.

This CL also generalises the Object.observe delivery loop into a simplistic microtask loop. Currently, all observer events are delivered before invoking any promise handler in a single fixpoint iteration. It's not clear yet what the final semantics is supposed to be (should there be a global event ordering?), but it will probably require a more thorough event loop abstraction inside V8 once we get there.

f3a22f965e The goal is to discover the appropriate heap space for objects created in full 
code. By the time we optimize the code, we'll be able to decide on new or old
space based on the number of surviving objects after one or more gcs.

The mechanism is a "memento" placed behind objects in the heap. It's currently
done for array and object literals, with plans to use mementos for constructed
objects as well (in a later CL).

The feature is behind the flag allocation_site_pretenuring, currently off.

81b22bbf96 A performance regression in array literal creation was caused by refactoring that eliminated a special fast case for shallow arrays. At the same time the general case got a bit slower. This CL restores most of the performance without coding the special fast case. The virtual dispatching is unnecessary because we know what we want to do at compile time. A flag was added to Runtime::CreateArrayLiteral. The flags delivers information about shallowness but also whether or not allocation mementos should be created. This is useful for crankshafted code.

3cf157b43b Inline zero argument array constructor. 
patch from issue 54583003 (dependent code).

Zero arguments - very easy

1 argument - three special cases:
  a) If length is a constant in valid array length range,
     no need to check it at runtime.
  b) respect DoNotInline feedback on the AllocationSite for
     cases that the argument is not a smi or is an integer
     with a length that should create a dictionary.
  c) if kind feedback is non-holey, and length is non-constant,
     we'd have to generate a lot of code to be correct.
     Don't inline this case.

N arguments - one special case:
  a) If a deopt ever occurs because an input argument isn't
     compatible with the elements kind, then set the
     DoNotInline flag.

This is controlled by two flags:

--redirect_code_traces
--redirect_code_traces_to=<filename>

When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).

D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

cec8548d0e Correct handling of arrays with callbacks in the prototype chain. 
Our generic KeyedStoreIC doesn't handle the case when a callback is
set on array elements in the prototype chain of the object, nor do
we recognize that we need to avoid the monomorphic case if these
callbacks exist.

This CL addresses the issue by looking for dictionary elements in
the prototype chain on IC misses and crankshaft element store
instructions. When found, the generic IC is used. The generic IC is
changed to go to the runtime in this case too.

In general, keyed loads are immune from this problem because they
won't return the hole: discovery of the hole goes to the runtime where
the callback will be found in the prototype chain. Double array loads
in crankshaft can return the hole but only if the prototype chain is
unaltered (we will catch such alterations).

Includes the following patch as well (already reviewed by bmeurer):
Performance regression found in test regress-2185-2.js. The problem was
that the bailout method for TransitionAndStoreStub was not performing
the appropriate transition.
