The LiteralsArray will soon hold a type feedback vector. Code treats it as an
ordinary fixed array, and needs to stop that.

This is mostly removing dead code and also dropping MUST_USE_RESULT

The return value is expected to be the number of padding slots added to the frame. However, the original logic would return -1 if padding was required, so insufficient stack space would be reserved.

This function now returns either 0 or 1, as the existing calling code expects.

This adds ES6 compliant Object::ToInteger, Object::ToInt32,
Object::ToUint32 and Object::ToLength, and replaces the old
Execution wrappers of those abstract operations (which were
not using the correct ToPrimitive).

This also introduces proper %ToInteger and %ToLength runtime
entries, with a fast path %_ToInteger supported in fullcodegen
and Crankshaft (for now). Internal JavaScript code should use
TO_INTEGER and TO_LENGTH respectively.

When all heuristics fail, we run a "last resort" heuristic. Before, it was
splitting at the first found splittable position either before or after a
use position. That turns out to be too naive: it may split in loops, when
alternative split positions exist outside loops.

This change chooses a "before" use case location that is outside the
loop.

Replacing it with SMI_ACCESSORS.
This change makes accesses to Smi fields in objects more regular (the
accessors now always consume/return an int rather than a Smi*), which
avoids a bunch of manual Smi::FromInt() and Smi::value() conversions,
and is a step on the way towards being able to generate objects-inl.h.
