Short summary of the changes:
 - The ecma_reference_t is removed, and its helper functions are deleted.
 - The delete operation does not depend on ecma_reference_t anymore.
 - A new resolve function is added which returns the current value
   of a named binding in the context chain.
 - The vm_op_set_value does not perform type conversions when its arguments
   has the appropriate types.
