Refactor object property chain to use property pairs. The patch

Browse Source 
itself seems a step back, but the primary aim is opening future
optimization opportunities. The list of changes follows:

 - Property is changed to be an abstract type, which has type, flags,
   and a value. It does not have a name anymore and property pointers
   cannot be compressed.
 - Full (32 bit) ecma values can be property values. This allows
   using non-compressed pointers for ecma values in the future.
 - The property chain is not restricted to the same item anymore,
   it can contain hash maps, arrays in the future.
