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).

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.
