Make NextCodeLink pointer 8-byte aligned after GC pointer updating uses atomics.

After r24737 pointer updating is done by atomic operations which strictly
require target address to be 8-byte alignment on MIPS64.

The alignment is broken on 64-bit arches because InstructionSize is first field
and has Int size.

Order of fields in object layout are changed to make kNextCodeLinkOffset
divisible by 8. The size of code object header remains the same.

A type vector with multiple IC types needs metadata.

This CL adds a bitset to describe the type of IC in each IC slot.
This is necessary for clearing ICs of different types.

With FLAG_vector_ics off (the current state), it's not required because
CALL_IC is the only type of IC in the vector.

TurboFan calls to vector-based ics need to resolve a slot to an index.

This is to cope with the recent division of the TypeFeedbackVector into
Slots and ICSlots.

Improve printing for Symbols.

Private symbols we create in the heap don't have names, but we can
resolve them to a constant string.

This gives handy debugger output like:

(gdb) job 0x2020c67d
0x2020c67d: [Symbol]
- hash: 547385396
- name: 0x20208091 <undefined> (uninitialized_symbol)
- private: 1
- own: 1
$7 = void
(gdb)

or with ShortPrint() in an array:

...
[5]: 0x2020c67d <Symbol: 547385396 (uninitialized_symbol)>
...

Printing help for internal symbols

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%.

Fix sparse versions of Array slice/splice to use [[DefineOwnProperty]] to generate return value

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/658743002/).

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).
