Fix: bytecode: Validate register type for instructions expecting unknown type

The bytecode validator allows unknown type as input for some
instructions which are not specialized. The interpreter therefore needs
to check the register type for their input.

Thie requires that every instruction in the interpreter sets the
register type of the output it populates (unless it is unchanged).
