67ff68783a Arm64: Fix check errors on Arm64 debug after r21177.
r21177 added extra AssertStackConsistency() checks which
increased code size on debug and caused the assembler buffer
to be too large.  Increased some of these buffers to
compensate.

Also, ProfileEntryHoolStub could use the wrong number of
instructions for kProfileEntryHookCallSize depending upon
whether debug code was being emitted or ALWAYS_ALIGN_CSP was
enabled.  Fixed this by taking ALWAYS_ALIGN_CSP into account
and ensuring that no debug code is emitted during
MaybeCallEntryHook().

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:

98cd283399 Remove symbol preparse data altogether.
Removing it seems to be a clear win on mobile: producing symbol data makes cold
parsing 20-30% slower, and having symbol data doesn't make warm parsing any
faster.

Notes:
- V8 used to produce symbol data, but because of a bug, it was never used until
recently. (See fix https://codereview.chromium.org/172753002 which takes the
symbol data into use again.)
- On desktop, warm parsing is faster if we have symbol data, and producing it
during cold parsing doesn't make parsing substantially slower. However, this
doesn't seem to be the case on mobile.
- The preparse data (cached data) will now contain only the positions of the
lazy functions.

5ea893074c Fix ObjectNotifierPerformChange leak after r21126
Due to overlapping names of natives and runtime functions, the wrong
context was used for Notifier.prototype.performChange. The leak test
has been augmented to properly cover the leaky case, and the test
now passes.

Also tightened up type checks in runtime.cc and removed Object.observe
functions from knownIssues in fuzz-natives-part2.js.

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.

bb1abb7f01 MIPS: CodeStubs contain their corresponding Isolate* now. (part 1)
Port r20919 (aa51355)

Original commit message:
This is a purely mechanical change, adding an Isolate* to the CodeStub
constructor and a corresponding field plus a getter. A few methods in
CodeStub and its subclasses can be simplified now, but this is done in
a separate CL.

The underlying reason apart from simplicity is that deep down in the
call chain we need to detect if the serializer is active or not. This
information will be part of the Isolate, not a global variable with
funky synchronization primitives around it (which is fundamentally
wrong and the underlying cause for race conditions and a catch-22
during initialization).

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.

5a016958c6 MIPS: Add big-endian support for MIPS.
Important notices:

- The snapshot cannot be created for big-endian target in cross-compilation
  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
  use of typed arrays.
