#5 confirmed that lazy flags are generally implementable and might be beneficial in terms of performance. This task is (to try) to support lazy flags for i8080 and see if it works as a proof of concept and how much speed-up we can have from that. Lazy flags for Z80 is to be addressed with a separate ticket.
