Array constructor shouldn't require a Cell, just an AllocationSite.
...
The Array constructor has a needless dependency on an input argument
that is a Cell. It uses this to walk through to an AllocationSite.
The dependency hampers future work. Instead, pass the AllocationSite
as input to the Array constructor.

Fix logic error in assert in IsUndeclaredGlobal()
...
Recent changes in IC logic meant that CallStubs no longer use the Contextual bit. IsUndeclaredGlobal() needed to adjust for that.
In fact, now the CL has morphed to remove the notion of storing contextual state in the IC at all, it just becomes some extra ic state of the load ic. This took some adjustment in harmony code to use the global receiver for certain stores.
Now it's clearer that only LoadICs actually record any information about contextual or not.

This is a preview of a first step towards unification of the hydrogen
...
call machinery. The change replaces CallNamed, CallKeyed,
CallConstantFunction and CallKnownGlobal hydrogen instructions with two
new instructions with a more lower level semantics:
1. CallJSFunction for direct calls of JSFunction objects (no
argument adaptation)
2. CallWithDescriptor for calls of a given Code object according to
the supplied calling convention.
Details:
CallJSFunction should be straightforward, the main difference from the
existing InvokeFunction instruction is the absence of argument adaptor
handling. (As a next step, we will replace InvokeFunction with an
equivalent hydrogen code.)
For CallWithDescriptor, the calling conventions are represented by a
tweaked version of CallStubInterfaceDescriptor. In addition to the
parameter-register mapping, we also define parameter-representation
mapping there. The CallWithDescriptor instruction has variable number of
parameters now - this required some simple tweaks in Lithium, which
assumed fixed number of arguments in some places.
The calling conventions used in the calls are initialized in the
CallDescriptors class (code-stubs.h, <arch>/code-stubs-<arch>.cc), and
they live in a new table in the Isolate class. I should say I am not
quite sure about Representation::Integer32() representation for some of
the params of ArgumentAdaptorCall - it is not clear to me wether the
params could not end up on the stack and thus confuse the GC.
The change also includes an earlier small change to argument adaptor
(https://codereview.chromium.org/98463007 ) that avoids passing a naked
pointer to the code entry as a parameter. I am sorry for packaging that
with an already biggish change.
Performance implications:
Locally, I see a small regression (.2% or so). It is hard to say where
exactly it comes from, but I do see inefficient call sequences to the
adaptor trampoline. For example:

bf85aa515a mov edi,0x5a51aa85 ;; debug: position 29
