Alexander Markov 0d1abc535b [vm/kernel/bytecode] Initialize _Closure._delayed_type_arguments to Object::empty_type_arguments() 
As TypeArguments == null means 'vector of all dynamic', VM uses special
object (Object::empty_type_arguments()) to indicate absence of
_Closure._delayed_type_arguments.

This CL corrects bytecode to use Object::empty_type_arguments() (via new
constant pool entry EmptyTypeArguments) to initialize
_Closure._delayed_type_arguments when allocating a closure.
