Added constructor call on object in InstantiateObject method
I found after upgrading from 4.2.2 where apinatives.js still
existed to 4.4.56 where everything had been converted to C++ in
api-natives.cc, my constructors for ObjectTemplate instantiated objects
were no longer being called. After investigation, I noticed in
apinatives.js that a new call would handle that, but there was no
corresponding constructor call in api-natives.cc (or anywhere else
along the chain of InstantiateObject), so I added a call to
Execution::Call to actually construct the object. Forgive me if that
isn't the right place to add it (InitializeBody in objects-inl.h also
looked like a good place), or if there's a reason constructors are
not being called.

AstGraphBuilder::BuildToBoolean() can be optimized easily without types,

Serializer: support all alignment kinds.
We use an alignment prefix for unusual alignment kinds (not kWordAligned).
This will cause new objects to be aligned in ReadObject, and back references
to be aligned to skip padding.
The motivation to change the undefined next sentinel in WeakCell is this:
When the deserializer aligns an object, it requires filler maps to already
exist to create filler objects as padding. However, deserializing the
filler map leads to deserializing NaN, which as heap number is aligned:
filler map > meta map > weak cell cache > undefined > NaN
If we use the-hole instead of undefined as sentinel, it works.

Serializer: support all alignment kinds.
We use an alignment prefix for unusual alignment kinds (not kWordAligned).
This will cause new objects to be aligned in ReadObject, and back references
to be aligned to skip padding.
The motivation to change the undefined next sentinel in WeakCell is this:
When the deserializer aligns an object, it requires filler maps to already
exist to create filler objects as padding. However, deserializing the
filler map leads to deserializing NaN, which as heap number is aligned:
filler map > meta map > weak cell cache > undefined > NaN
If we use the-hole instead of undefined as sentinel, it works.

Apparently the *RealNamed* API methods only have named variants, but were always used by the embedder to find elements as well. We'd never find them though, since we wouldn't even look

[turbofan] Use appropriate type for NodeId.
Up until now we used int32_t for NodeId, but that was not ideal because
negative values are invalid for NodeId and we use it as an array index
for example in the NodeMarker class, where C++ compilers on x64 have to
generate code that does proper sign extension for the indices, which is
completely unnecessary.

MIPS64: Fix memory allocation when code range is used for LO space only.
Allocation must respect requested reserve size, not requested commit area size.
Additionally fix check failures in debug mode for mips64.
After CL: https://codereview.chromium.org/
1147503002/
memory for large code objects is allocated from code range,
memory for regular code objects is allocated normally.
