02fdc4114f Promote ArrayBuffer, DataView and typed arrays to non-experimental. 
The primary reason for this change is to bake these guys into the
snapshot.

Flag definitions (--harmony-typed-arrays, --harmony-array-buffer) are
still there so that Blink does not complain, but they are noop and

ec8c6f4692 Rename AllocationSiteInfo to AllocationMemento 
This is just a rename change with the exception of a bug found along the way in
CodeStubGraphBuilder<FastCloneShallowArrayStub>::BuildCodeStub(). There, the
intent is to get the boilerplate object from an AllocationSite. But the wrong
HObjectAccess was used. It only succeeds because it happened to be the same
offset :).

00ed79fb8b Move FindCodeObject from Heap to Isolate. 
This removes the isolate=>heap=>isolate nonsense and has the additional bonus
that it re-enables printing of code objects in GDB. NOT: To make the latter
work, one has to adapt GDB any macros using FindCodeObject! Keeping things as it
is and outlining Isolate::heap() was not really an option...

Side note: Currently we are lucky that we still have Isolate::Current()
available in GDB, although it is marked as INLINE. :-}

35052bc2ea Reland deprecation of HAllocateObject in favor of HAllocate. 
This essentially relands r14930 and r14935 with adaptions to the current
code base. It models the instantiation of an implicit receiver for
CallNew nodes in hydrogen using HAllocate together with generic stores
instead of one specialized HAllocateObject instruction, hence creating a
single choking point for inlined allocation in optimized code.

f8db2414f2 Deprecate FACTORY helper macro. 
This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.

55f93b5532 Renamed "symbols" to "internalized strings" throughout the code base, 
in preparation of the introduction of ES6 'symbols' (aka private/unique names).

The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders.

The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

cee59bf522 Enable incremental code flushing. 
This enables code flushing even with incremental marking enabled and
fully shares the function link field in JSFunctions between candidates
for code flushing and the optimized functions list. If a candidate for
code flushing gets optimized, it will be evicted from the candidates
list.

84935fb23a Fix missing slot recodring during clearing of CallICs. 
This fixes a rare corner case that was caused by missing recording of
relocation slots when the uninitialized CallIC stub happenes to land on
an evacuation candidate and the IC is cleared via the shared function.

5a8d1764bc Refactoring of snapshots. This simplifies and improves 
the speed of deserializing code.  The current startup
time improvement for V8 is around 6%, but code deserialization
is speeded up disproportionately, and we will soon have more
code in the snapshot.
* Removed support for deserializing into large object space.
  The regular pages are 1Mbyte now and that is plenty.  This
  is a big simplification.
* Instead of reserving space for the snapshot we actually
  allocate it now.  This removes some special casing from
  the memory management and simplifies deserialization since
  we are just bumping a pointer rather than calling the
  normal allocation routines during deserialization.
* Record in the snapshot how much we need to boot up and
  allocate it instead of just assuming that allocations in
  a new VM will always be linear.
* In the snapshot we always address an object as a negative
  offset from the current allocation point.  We used to
  sometimes address from the start of the deserialized data,
  but this is less useful now that we have good support for
  roots and repetitions in the deserialization data.
* Code objects were previously deserialized (like other
  objects) by alternating raw data (deserialized with memcpy)
  and pointers (to external references, other objects, etc.).
  Now we deserialize code objects with a single memcpy,
  followed by a series of skips and pointers that partially
  overwrite the code we memcopied out of the snapshot.
  The skips are sometimes merged into the following
  instruction in the deserialization data to reduce dispatch
  time.
* Integers in the snapshot were stored in a variable length
  format that gives a compact representation for small positive
  integers.  This is still the case, but the new encoding can
  be decoded without branches or conditional instructions,
  which is faster on a modern CPU.

This extends the existing clearing of ICs during GC to incremental
marking in order to prevent cross-context retention that would last
until the next non-incremental GC.
