#2 - Readd class _Int | Update definition of _Int32 and _Int64 so they inherit from _Int | Update builtin tests

Readded the _Int class so that methods which take an int as an argument can be created and int64 and int32 inherit from it so that when those methods which take _Int arguments are called we can pass either int64 or int32 s.
