3e328bf254 [turbofan] Add support for special JSArrayBufferView accessors.
Lower access to byteOffset and byteLength getters on JSArrayBufferViews
and to length on JSTypedArrays. This requires a check to see whether the
backing JSArrayBuffer was neutered.

5019ce6ef3 PPC: [turbofan] Move JSCallFunction specialization to JSCallReducer.
Port e5edd66d07

Original commit message:
    This is the first part to refactoring the JSNativeContextSpecialization
    class, which has grown way too big recently.

    Also don't collect cross context feedback for the CallIC in general.
    Neither TurboFan nor Crankshaft can make any use of cross context
    JSFunction feedback that is collected by the CallIC, so there's no
    point in gathering that feedback at all (it just complicates the
    checking that is necessary in the compilers). What we should do
    instead at some point (when Crankshaft becomes less important) is
    to collect the SharedFunctionInfo as feedback for those cases.

24ff30b740 [es6] refactor Promise resolution
Several changes are included here:

1. Each resolution callback references shared data indicating whether
it has already been resolved or not, as described in 25.4.1.3
http://tc39.github.io/ecma262/#sec-createresolvingfunctions.
Previously this was handled exclusively by the Promise's status,
which does not work correctly with the current chaining behaviour.

2. During fulfillment, When a Promise is resolved with a thenable, the
spec chains the promises together by invoking the thenable's `then`
function with the original Promise's resolve and reject methods (per
section 25.4.2.2, or
http://tc39.github.io/ecma262/#sec-promiseresolvethenablejob, on the
next tick, regardless of whether or not there are pending tasks.

3. Adds a spec compliance fix to ensure that the Promise constructor
is only loaded once when `then()` is called, solving v8:4539 as well.
This involves refactoring PromiseChain to accept a constructor
argument. PromiseChain/PromiseDeferred will hopefully be removed soon,
simplifying the process.

d9305784f9 X87: [turbofan] Move JSCallFunction specialization to JSCallReducer.
port e5edd66d07 (r32022)

    original commit message:
    This is the first part to refactoring the JSNativeContextSpecialization
    class, which has grown way too big recently.

    Also don't collect cross context feedback for the CallIC in general.
    Neither TurboFan nor Crankshaft can make any use of cross context
    JSFunction feedback that is collected by the CallIC, so there's no
    point in gathering that feedback at all (it just complicates the
    checking that is necessary in the compilers). What we should do
    instead at some point (when Crankshaft becomes less important) is
    to collect the SharedFunctionInfo as feedback for those cases.
