4097318792 Treat pointers in optimized code as strong before all weak dependencies are registered. 
This prevents GC from observing code objects with out-of-sync weak dependencies.

e4c5b84652 Contribution of PowerPC port (continuation of 422063005) 
Contribution of PowerPC port (continuation of 422063005). The inital patch
covers the core changes to the common files.  Subsequent patches will cover
changes to common files to support AIX and to update the ppc directories so
they are current with the changes in the rest of the project.

4fa7ae1c07 Optimize Object.seal and Object.preventExtensions 
They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.

This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).

243764b04b Optimize add/set/delete operations for string keys in Maps and Sets 
This was previously landed in commit 8599f5f, but failed the
collections mjsunit test on ia32 with --deopt-every-n=1. The fixed
patch adds a ClearFlag(HValue::kCanOverflow) call after every
arithmetic operation, which should remove all the deopt points in these
intrinsics.

Ideally, it seems like there should be a way to verify that there are
no deopt points for these inline optimized functions, since there's
nothing to deopt to. But I don't currently know of such a thing.

This combines Map::DoneInobjectSlackTracking and Map::ConstructionCount into one more generic 4-bit counter.

Counter values from 15 down to 8 are used for in-object slack tracking, values from 7 down to 0 are free to be used for a new counter when in-object slack tracking is inactive.

93cd816c07 Make TemplateLiteral hashing algorithm more memory efficient 
Previously, a separate string to be hashed (in order to help determine the need to
use a cached Template Call Site) was built up by joining UTF8 spans within a template.

Now, the hash key is generated from the original spans, removing the need to allocate a new
buffer and copy bytes into it.

1a64b02dcf harmony_scoping: Implement lexical bindings at top level 
This implements correct semantics for "extensible" top level lexical scope.
The entire lexical scope is represented at runtime by GlobalContextTable, reachable from native context and accumulating global contexts from every script loaded into the context.

When the new script starts executing, it does the following validation:
- checks the GlobalContextTable and global object (non-configurable own) properties against the set of declarations it introduces and reports potential conflicts.
- invalidates the conflicting PropertyCells on global object, so that any code depending on them will miss/deopt causing any contextual lookups to be reexecuted under the new bindings
- adds the lexical bindings it introduces to the GlobalContextTable

Loads and stores for contextual lookups are modified so that they check the GlobalContextTable before looking up properties on global object, thus implementing the shadowing of global object properties by lexical declarations.

After r24737 pointer updating is done by atomic operations which strictly
require target address to be 8-byte alignment on MIPS64.

The alignment is broken on 64-bit arches because InstructionSize is first field

8189922e1e Limit the number of transitions allowed per hidden class. 
Each time a transition is added to a hidden class, the whole
transitions array must be copied, which causes poor performance
in some circumstances.  This change limits the maximum size of
the transition array, avoiding this behavior in the pathological
case.  For example, this improves the performance of the EtchMark
benchmark by nearly 60%.

5f1ae66d56 Narrow cases where Sparse/Smart versions of Array methods are used 
Added a new %HasComplexElements runtime function (meaning elements that are
non-writable, non-configurable, or have getters and setters) and use it
in UseSparseVariant to filter out cases where the sparse optimizations
can cause V8 to fall out of spec compliance.

Renamed SmartMove/SmartSlice to SparseMove/SparseSlice and guarded them
with the new and improved UseSparseVariant.

These two changes combine let us pass nearly every test in bug-2615.js,
as well as fixing reverse and join on sparse arrays.

Note that there are various test changes in this patch that correct existing
tests to match the correct-by-spec behavior.

This patch depends on https://codereview.chromium.org/666883009, which
better-aligns the behavior of SmartMove with SimpleMove.

"arguments". The information is exposed via Scope::uses_this(),
and Scope::uses_arguments(), respectively. Flags for tracking
usage on any inner scope uses are available as well via
Scope::inner_uses_this(), and Scope::inner_uses_arguments().

Knowing whether scopes use "this" and "arguments" will be handy
to generate the code needed to capture their values when generating
the code for arrow functions.

ecac8b0877 Eliminate special keyed load string stub in favor of uniform handlers. 
KeyedLoadIC installs a special case if the receiver is a string.
Although there are several maps for strings, in practice we seem to
be able to treat them individually because a given KeyedLoad site
only sees 1-2 string types.

3727a10d20 Use WeakCell to handle the script wrapper cache 
The script wrapper cache used the API weak handles to provide a weak link from Script to ScriptWrapper. We want to change the way API weakness works, and in this context it's best to get rid of users of the API that don't need to be users.

d8295050d2 Fix deoptimization address patching in Turbofan to use safepoints. 
Since the deopt patch address needs to be available during GC to
resolve safepoints, we need to move it to the code object (instead of
the deoptimization input data) - accessing a separate fixed array
is not safe during GC. This CL adds a deoptimization_pc field to
each safepoint. The fields points to the deoptimization block.

The CL also fixes wrong register allocator constraints for
frame states on calls. These should always live on the stack
because registers are not preserved during a call.

168742b81a Introduce a PrototypeIterator class and use it for prototype access 
The new pattern is that we first get the map of the root of the
prototype chain using Object::GetMapRoot() and then walk up the
prototype chain using Map::prototype().

3994880715 Support ES6 Map and Set in heap profiler 
Added special handling for Map and Set in the heap snapshot generator.

Extracted common base type from JSMap/JSSet similar to JSWeakMap/JSWeakSet.

After handling collection specific properties all collections are processed as regular JSObject to make sure all regular properties set on them are present in the heap snapshot.

05463c4906 Avoid unnecessary hashing in OrderedHashTable 
Add an overload of OrderedHashTable::FindEntry that takes
a hash along with the key to allow callsites which need to
re-use the hash (such as Add()) to avoid recomputing it.

On my Macbook this results in improvements on the Collections
microbenchmarks:
  Map-Collections: +4%
  Set-Collections: +5%
