Introduce FeedbackNexus for vector-based ics.
A FeedbackNexus is the combination of a feedback vector, a slot(s) in
the vector, along with methods to query and manipulate that information
in a type-correct way.
A CallIC will have a CallICNexus, a LoadIC a LoadICNexus, etc.,
reflecting the fact that different types of ICs configure their data
in unique ways.
This CL limits itself to introducing and using the nexus type only for
CallICs. A follow-up will use them for Load and KeyedLoadICs for the
case when the --vector-ics flag is turned on.
The notion of a Nexus is also embedded at the lowest level of the IC
class. This makes sense because more ICs should become vector-based
in the future.
This CL is based on https://codereview.chromium.org/
679073002/ which
should land first.

Limit the number of transitions allowed per hidden class.
Each time a transition is added to a hidden class, the whole
transitions array must be copied, which causes poor performance
in some circumstances. This change limits the maximum size of
the transition array, avoiding this behavior in the pathological
case. For example, this improves the performance of the EtchMark
benchmark by nearly 60%.

Narrow cases where Sparse/Smart versions of Array methods are used
Added a new %HasComplexElements runtime function (meaning elements that are
non-writable, non-configurable, or have getters and setters) and use it
in UseSparseVariant to filter out cases where the sparse optimizations
can cause V8 to fall out of spec compliance.
Renamed SmartMove/SmartSlice to SparseMove/SparseSlice and guarded them
with the new and improved UseSparseVariant.
These two changes combine let us pass nearly every test in bug-2615.js,
as well as fixing reverse and join on sparse arrays.
Note that there are various test changes in this patch that correct existing
tests to match the correct-by-spec behavior.
This patch depends on https://codereview.chromium.org/
666883009, which
better-aligns the behavior of SmartMove with SimpleMove.

Change SmartMove no-op behavior to match SimpleMove (and ES6 spec)
The previous behavior, which caused Array.prototype.unshift() (with no args)
to have side-effects, no longer matches the spec (ES6 changed the no-arg behavior
in April 2014). The new SmartMove behavior is also compatible with current
versions of Firefox.
This is a baby step towards getting rid of SmartMove; it isolates the test
change in this patch, instead of lumping it in confusingly with all the
other test updates necessary for moving away from SmartMove.

[turbofan] Use range types to type and lower arithmetic ops.
This is based on Georg's work on typing arithmetic operations (https://codereview.chromium.org/

Instead of weakening to bitset types, we weaken to the closest 2^n
limit if we see that we are re-typing a node with a range type (which
means that the node can be part of a cycle, so we might need
to speed up the fixpoint there).
