A function could be deoptimized due to a deopt in the inlined code.
The inlined function might be defined in another script. So we need to

We already have the tracking code which is behind FLAG_hydrogen_track_position.

Property reconfiguring implemented.
Previous approach for property reconfiguration was to create a free-floating map with generalized representations of all fields. This patch does it right.
When property is reconfigured either by changing its kind (kData <-> kAccessor) or its attributes it implies creation of a new branch in transition tree. If such a branch already existed before reconfiguration then it should be merged with the old (or source) branch of the transition tree. Merging procedure includes all the heavy machinery such as property location changes (kDescriptor -> kField), field representation/field type generalization, map deprecation, etc.
