I think you can forget about flags.
According to Agner Fog and his "instruction_tables" on PentiumM the 2
instruction will not be executed at the same time, and will take 2uop.
On Core2 arch they will be executed t the same time but still take
2uops.
Specify your CPUs people if you wanna talk about speed.
