In the ThisNamedPropertyAssignmentFinder, duplicate assignments to the same
property were counted as distinct assignments.  As a simple fix, subsequent
ones overwrite the previously recorded assignment.

This will reorder the assignments, but it is safe since they are restricted
to have only constants and parameters on the right-hand side (and there are
no assignments to the parameters).

Instead of expecting Object** arrays at the outermost level, expect
Handle<Object> arrays and reinterpret_cast them only just before invoking

This fixes a bug where the length of FAST_DOUBLE_ELEMENTS arrays was not
set correctly, and another bug where appending a double element to a
SMI_ONLY array would convert it to FAST_ELEMENTS instead of
FAST_DOUBLE_ELEMENTS.

Previously, the logic using the hidden properties backing object was
spread accross use sites. Now it's all contained in JSObject, with
only simple accessors available.
Also change the backing object to be a StringDictionary rather than a JSObject.
There's still room for improvement by making a hash-table that don't
store property details as well.

The API is inconsistent about when a register must be coerced to an operand
and when it can be used as a register.  Simplify usage by never requiring it
to be wrapped.

While traversing the transition tree we build a work-list using the map
field of maps. Setting those map values with a write barrier causes
black-to-gray changes on maps which are currently not recognized as
such, hence their computed size might be off.
