There exists specialized software to persist your IRC sessions:

https://en.wikipedia.org/wiki/BNC%20(software)

Alternatively, just SSH into a remote (and possibly anonymously setup) 
server and connect to IRC there. Your presence on IRC then only reflects 
the availability of the server, not the availability of you and/or your 
client.

Bonus points if you use Tor twice: once to SSH into the server, and once 
to connect to IRC. It won't matter much for end-to-end timing 
correlation attacks though.

Tor doesn't act differently. Tor only sees a TCP connection. It's just 
that HTTP transactions usually don't persist long, and IRC transactions 
do. You cannot change exit nodes while persisting a connection. Thus 
your HTTP transactions hop exit nodes on a 10-minute interval, and your 
IRC connections do not (until you reconnect).
