34a1a76ddf Use platform specific stubs for vector-based Load/KeyedLoad. 
A hydrogen code stub is not the best approach because it builds a frame
and doesn't have the technology to discard roots at tail call exits.
Platform-specific stubs provide much better performance at this point.

d8416f5524 Intrinsics in the INLINE_FUNCTION_LIST are now avaliable without '_', too. 
This involved renaming apart a few more intrinsics. In the long run,
we want to clean up redundant intrinsics which just delegate.

6fc97a1965 Retry "Use a WeakCell in the CallIC type vector." 
The first try failed because I needed to make a better distinction
between clearing ICs according to policy at GC time or unconditional
clearing (say, via %ClearFunctionTypeFeedback).

It was also blocked by an issue in super constructor calls.
This fix (https://codereview.chromium.org/892113002/) needs to land
before checking in this CL.

The HydrogenCodeStub is too expensive and there's no easy way to reduce
this cost, so turning it into a PlatformCodeStub solves that problem
until we can use TurboFan for code stubs.

a4176d2052 Removing ic.h from code-stubs.h 
CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.

More work could/should be done here, but this is a first step.

90c8932596 Replace our homegrown ARRAY_SIZE() with Chrome's arraysize(). 
Our own ARRAY_SIZE() was pretty bad at error checking. If you use
arrasize() in a wrong way, the compiler will issue an error instead of
silently doing the wrong thing. The previous ARRAY_SIZE() macro is still
available as ARRAYSIZE_UNSAFE() similar to Chrome.

7b9e24e3fb Clean up IC tracing for CallICs. 
CallICs have had some confused tracing, because the IC state is not
entirely captured by the installed code stub - it lives in the type
vector.

Change tracing to be able to use the vector state changes instead.
Introduced a DEFAULT state to be used by all vector-based ICs.
