Follows 34b1920e7b.
This splits off the object-related functions, such as
[Set/Get/Has]Property, CreateObject, CreateArray, FreezeObject.
It also puts the definitions in the header itself, which might end up
with faster code here & there, though perhaps slower compilation time
(somewhat doubtful since we already included most things anyways).
