--harmony-computed-property-names, for both object literals and

The MISS handler was being called when the receiver was a Smi, instead,
we should recognize the case and use the heap number map.

Math functions:
Some Math functions require typed arrays for their implementation. The embedded
script may call those Math functions. The serializer needs to deal with this.
Added assertion to make sure no other typed array is created when snapshotting.
Number-string cache:
We assume that the initial snapshot does not expand the number-string cache.
This is no longer true for custom heap snapshots.
Bound functions:
Bound functions store the bound arguments in a COW fixed array, including the
bindee function. COW arrays are serialized into the startup snapshot and
referenced in the partial snapshot via partial snapshot cache. However, the
bindee function is context-dependent and must not be part of the startup
snapshot. There is no need for bound functions to use a COW array though.

Support for it is slow and difficult to implement, and it's not used in
Blink. An embedder that uses this feature will have to check the
argument types itself.

Since we have a special guard page at the beginning of the code range on
win64, we need to make sure to adjust the size of the free list
accordingly when creating it.

- Move NodeMarker to its own file, and introduce a non
templatized base class.
- Cleanup the include hell.
- Sanitize the Node construction methods now that we
got rid of that GenericNode/GenericGraph stuff.
- Protect against NodeId overflow in Graph.
- Various minor cleanups.

Introduce a new AnyToBoolean simplified operator to handle the later
lowering of boolean conversions. Previously we tried to hack that with
the generic JSToBoolean, having its context set to zero, but that lead
to various problems/bugs and did not handle all cases.

This API is used by Blink to inform V8 about HTML frames being disposed.
Using the optional parameter, Blink can tell V8 whether the disposed
frame was a main frame. In that case, we might want to reset GC
parameters

There might be a number of clients that would like to
setup an interrupt request on the Isolate.
The patch also deprecates ClearInterrupt API. As long as
the interrupt handler is called outside of locks there's no way
to guarantee that the handler will not be called after
ClearInterrupt was invoked as it might have already started execution.
