Igor Sheludko 808a3f23bc [ptr-compr] Introduce TaggedIndex class 
... a Smi-looking type containing properly sign-extended int31 integer.

The idea is to use this kind of tagged integers for the cases where
the value is guaranteed to fit into int31. For example, feedback vector
slots is one of the candidates for using TaggedIndex representation.
