Currently the validator, when checking an instruction is in the correct section, always advances the current section. This means if we have an instruction from a previous section we'll end up reporting it as invalid in a function definition. This error is confusing. This CL updates the validator to check if the given opcode is from a previous layout section before advancing the current section. If it is from a previous layout section an error is emitted.
