1211f606ae Cache IC handlers on the prototype's map if possible 
instead of on the receiver's map. Lazily overwrite cached handler if it is
identical to the handler that just missed.

ae6496e6ea [Arm]: Optimize ConstantPoolBuilder::Populate code by minimizing calls to OffsetOfElementAt 
Calling OffsetOfElementAt becomes expensive when compiling functions with many
constant pool entries.  This was causing a regression in MandreelLatency due
to the time spent populating the constant pool array for large compiled
functions.

This change avoids calling OffsetOfElementAt for each entry, and instead keeps
track of the current offsets in ConstantPoolBuilder::Populate.  This gives the
following improvements on a Nexus 5:

                     Inline CP  |  OOL CP (before CL)  |  OOL CP (after CL)
Mandreel:               4305    |        3961          |       4120
MandreelLatency:        2298    |        1198          |       1994
Octane Score:           5197    |        4982          |       5152

018ef484b9 More OStreamsUse OStreams more often. 
This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

40af47d46a [Arm]: Enable use of extended out-of-line constant pool for Arm. 
- Adds support to the Arm assembler to use extended constant pools.
 - Update (set_)target_address_at to support extended constant pool load
   updates.
 - Replace Operand::is_single_instruction with Operand::instructions_required
   Due to the fact that different constant pool load types require different
   numbers of instructions.
 - Various cleanups of ConstantPoolBuilder to cleaner integration of the
   extended constant pool building.
 - Update GetRelocatedValue such that offsets to both map_check and bool_load
   are explicitly provided, rather than location of bool_load being inferred
   based on map_check, since the code inbetween is no longer of a predictable
   size.
 - Update MacroAssembler::GetRelocatedValueLocation() to add support for
   getting a value from an extended constant pool entry.
 - Update Debug::SetAfterBreakTarget() to use target_address_from_return_address
   when checking for debug breaks at constant pool load points.
 - Change ConstantPoolIterateBody to iterate over both heap and code pointer in
   the small section before moving onto the extended section, to work around the
   requirement of the serializer that pointers are iterated in-order.
 - Increase old_pointer_space SizeOfFirstPage() to offset the fact that constant
   pools are now in the old pointer space (rather than code).

This is a step in the direction of disentangling all uses of SetOwnPropertyIgnoreAttributes so we can provide a more specific implementation for those usecases, and reduce the capabilities of those clients, avoiding subtle bugs.

InitializeProperty only supports adding properties to extensible objects that do not contain the property yet. JSGlobalProxies cannot have properties themselves, so are not supported either.

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.

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.

3274485c50 Store JSGlobalProxy's identity hash directly on the proxy itself 
Previously, the hash was stored on the underlying global object, since
it was stored in the hidden property table. This patch moves to an
implementation modeled on JSProxy, adding a new 'hash' field to JSGlobalProxy.

This allows storing the global proxy in a Map, Set, WeakMap, or WeakSet and
accessing it even after the proxy has been attached to a new global, which
is Firefox's current behavior and was the consensus of a recent thread on public-script-coord:

1b270ef5ea Re-enable Object.observe and add enforcement for security invariants. 
This patch reverts r21062 which disabled Object.observe and the relevant tests.

It also adds enforcement for the following three invariants:

1) No observer may receive a change record describing changes to an object which is in different security origin (context have differing security tokens)

2) No observer may receive a change record whose context's security token is different from that of the object described by the change.

3) Object.getNotifier will return null if the caller and the provided object are in differing security origins

Further, it ensures that the global object can never be observed nor a notifier retrieved for it.

Tests are included.

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.

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.

  environment on little-endian host using simulator.

- In order to have i18n support working on big-endian target, the icudt46b.dat and
  icudt46b_dat.S files should be generated and upstreamed to ICU repo.

- The mjsunit 'nans' test is endian dependent, it is skipped for mips target.

- The zlib and Mandreel from Octane 2.0 benchmark are endian dependent due to

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.

9cf3909975 Track field types. 
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.

ff953ac055 Make maps in monomorphic IC stubs weak. 
Maps in monomorphic Load, KeyedLoad, Store, KeyedStore, and CompareNil IC
stubs are treated as weak references by the marking visitor.

During generation of an IC stub with a weak map, the stub is appended to the
dependent code array of the map. When the map dies, all stubs in its dependent
code array are invalidated by setting embedded maps to undefined.

b61696dd95 ARM: Do not set FPSCR when converting to clamped uint8 
Setting the FPSCR flags is expensive on some CPUs. Get rid of repeated
setting of the FPSCR by relying on the correct default flags being set
when doing uint8 clamping. Also use vcvt_u32_f64 instead of vcvt_s32_f64,
which enables removing the check against zero (vcvt_u32_f64 will clamp to
zero).

To be on the safe side, add asserts to check that the VFP rounding mode
flags are set to default as expected.

This increases performance of a hot loop repeatedly setting
Uint8ClampedArray values on some CPUs by as much as a factor of 12.

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.
