Reason: vector in in init folder was introducing an overload (`::`) for all Lean users. The workaround (use `local infix ::`) was counterintuitive. We currently have no special support for bitvectors in the code generator. Thus, there is no need to have vector and bitvec in the init folder right now. Moreover, the new parser and elaborator (issue #1674) should provide better ways of managing overloaded symbols.
