5392e94e8b ClearTypeFeedbackInfo(): context may not be initialized.
SharedFunctionInfo::ClearTypeFeedbackInfo() wants to compare feedback
to the array JSFunction, but it's called at times when the context
isn't fully initialized. Be cautious about this check.

3d0bf69cd8 Attempt no. 3 to fix Heap::IsHeapIterable and HeapIterator.
Now we remember new space's top pointer after the last GC to find out if there was a new space allocation since the last GC.

Unfortunately, this not completely safe - the debugger has a callback hook (that can call to JS) at the end of the GC epilogue that can in theory allocate and possibly make the heap non-iterable. We can only hope this does not happen.

a7e816db28 Introduce a separate event for CodeDeopt
The reuse of CodeCreateEvent for deopt events caused a CodeCreateEvent
fired twice for a code object. When the event was processed for the first
time it seized the no-fp-ranges from code object, so the second event
had no ranges info leaving code entry without them.
As a result when a cpu profile sample falls into the region it missed the
2nd stack frame.

eabf06021c MIPS: Avoid flushing the icache unnecessarily when updating target addresses in code.
Port r21380 (ef20a0a)

Original commit message:
This CL updates RelocInfo update operations and set_target_address_at to enable
skipping of the icache flush if it going to be batched up later.
Code::CopyFrom and Code::Relocate are modified to avoid individual icache
flushes since the whole code area will be flushed after the reloc info is
updated.

These changes reduce a regression when enabling the OOL constant pool on Arm,
since this change can cause MovT/MovW instructions for relocatable targets
if the constant pool is full.

Scores for Mandreel latency on a Nexus 5:
- OOL CP disabled: 3533
- OOL CP enabled, without this CL: 1825
- OOL CP enabled, with change: 3015

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.

dd4c82bbb3 Fix Heap::IsHeapIterable.
We only consider heap iterable if the new space is empty (in addition to the exisiting old space check).

The change also moves the iterability forcing + allocation prevention gadgets to HeapIterator so that it is impossible to miss them when iterating the heap.

2fee5a16ee Parser: delay throwing errors.
This makes Parser a bit more independent of Isolate during the recursive descent
phase. That is necessary for making it possible to run Parser on a non-main
thread in the future.

Proof of concept CL for the the "Parser independent of Isolate" work is here:

fd4da6bfe7 Get rid of HStoreNamedField::SkipWriteBarrier().
The write barrier elimination does the right thing now, so
we can get rid of this hack.

b09989ec58 Refactor transitioning stores.
There's actually no need to have the transition as part of the HStoreNamedField instruction. In fact, it is cleaner and faster to generate a separate HStoreNamedField for the transition map. This will also help to eliminate map stores with store elimination, as well as reduce register pressure for transitioning stores on ia32.

63199d0bfe Avoid flushing the icache unnecessarily when updating target addresses in code.
This CL updates RelocInfo update operations and set_target_address_at to enable
skipping of the icache flush if it going to be batched up later.
Code::CopyFrom and Code::Relocate are modified to avoid individual icache
flushes since the whole code area will be flushed after the reloc info is
updated.

These changes reduce a regression when enabling the OOL constant pool on Arm,
since this change can cause MovT/MovW instructions for relocatable targets
if the constant pool is full.

Scores for Mandreel latency on a Nexus 5:
 - OOL CP disabled: 3533
 - OOL CP enabled, without this CL: 1825
 - OOL CP enabled, with change: 3015
