37928334a1 Serialzier: expand string table as last step before deserializing. 
Not doing so could result in this scenario:
- We ensure that the string table is large enough. It is.
- We compile code stubs, which triggers a GC.
- The GC clears string table entries.
- This increases the number of deleted entries in the table.
- When the deserializer hooks up internalized strings into the
  table, we ensure that the table is large enough every time.
- Due to changed number of deleted entries, the heuristic
  decides to expand the string table.
- Allocation during deserialization causes assertion to fail.

fda60dc214 ARM: make predictable code size scope more precise in DoDeferredInstanceOfKnownGlobal. 
We block constant pool up to the call stub instruction, but the check for code size
includes the next instruction after the call instruction. That instruction can
emit constant pool.

3d98b956b5 Add d8 API for spawning function on a new thread. 
This API closely matches the Worker API. The differences:

1) The argument to the Worker constructor is a function to run, not a script.
2) Receiving a message from a worker is a synchronous API (as there is no event
loop).

The serialization done here is not robust as the real DOM implementation. For
example, recursive data structures or otherwise duplicated objects are not
allowed.

1bb051b8a4 [es6] Fix completion values of for loops with lexical variables 
Currently, the desugaring of for loops of the form for
(let/const ...; bla; bla) causes them to always have a
completion value of 1, regardless of whether the loop body
is executed or not. This CL fixes this, realigning
initializer blocks as a more general purpose way to avoid
the completion value rewriter (since that's all they really
do anyway).

92e6bcf13c [turbofan] Improve interplay of ControlReducer and CommonOperatorReducer. 
This turns the CommonOperatorReducer into an AdvancedReducer and makes
it independent of JSGraph (which was used only because it was convienent),
and let's the CommonOperatorReducer run together with the ControlReducer.

The ControlReducer is still not able to run together with other reducers,
but we're getting closer. The plan is to split the ControlReducer into
two parts: The dead code elimination part and the common operator
reduction part. This separation will help to avoid tricky bugs in the
future and should make testing a *lot* easier.

a3106d228e [turbofan] Remove another premature optimization from ControlReducer. 
We never hit the phi case for DecideCondition in practice, since a more
general optimization is already performed by typing and constant
propagation.

Currently this verifier will post an informative error if the author has not signed CLA, instead of rejecting the CL.

9a92d294f3 Use output parameter to distinguish error from absent result 
Otherwise we'd have to probe for pending exceptions.

I'll do the same to other interceptors in follow-up CLs

afc2fb26a1 [turbofan] Remove another ineffective optimization from the ControlReducer. 
The condition of a Branch or Select can never be a NumberConstant,
because the resulting graph would be invalid, so we don't need to
optimize this case. It can only ever be a tagged boolean or an untagged
bit.

Drive-by-fix: Test the interesting cases in the unit tests instead.
