64f81870ee Super Constructor Calls need to use a vector slot, not an ic slot. 
The Ast Call node is accustomed to using a vector IC slot for the
cases when it uses a CallIC. The super constructor work alters this
somewhat by using a CallConstructStub instead, however the
CallConstructStub expects a vector slot and not a vector ic slot.
This distinction needs to be maintained because slots and ic slots
have different clearing strategies and are handled differently.

d8cfbc633d [turbofan] Split pure nodes in the scheduler if beneficial. 
If a (pure) node has two or more uses, but there exists a path from the
common dominator of these uses to end, which does not contain a use,
then we split the node such that no unnecessary computation takes place.
Note however, that this only applies if the node cannot be hoisted out
of a loop.

aeec653f49 Revert of Add WeakMap to v8.h (patchset #3 id:40001 of https://codereview.chromium.org/886473005/) 
Reason for revert:
Broke compilation on component build http://build.chromium.org/p/client.v8/builders/V8%20Win32%20-%20nosnap%20-%20shared/builds/5007/steps/compile/logs/stdio

Original issue's description:
> Add WeakMap to v8.h
>
> A new map wich references its keys weakly is added to v8.h. Internally it uses the same storage as JSWeakMap but doesn't depend on the JavaScript part of WeakMap implementation in weak-collection.js, hence it can be instantiated without entering any context.

4e9e1eedf1 [V8] Added line, column and script symbols for SyntaxError 
For exception in promise we generate v8::Message API object from exception object. And in cases of Syntax or Reference Error we don't have enough information in exception object - we can't restore Error location from top stack frame.
In this patch three aditional private fields introduced for exception object. In case of Syntax Error we store line, column and script on Exception object and receive this information when restoring message.

6019cbf9df MIPS64: Megamorphic KeyedLoadIC needs special handling for vector ics. 
Port 16843e239d

Original commit message:
When --vector-ics is true, we still tail-call to the hand-written
megamorphic KeyedLoadIC (formerly "generic"). Now that this code uses
the megamorphic cache, it needs to deal properly with the vector and
slot registers. Achieve this with a sentinel vectors/slot combo.
