IRLM address space would use most of the CPU -- not CICS or DB2 address space. There is also some CPU used in MSTR and DBM1, fwiw. Lock processing is very efficient for modern Db2 releases so this is not normally a problem. If you are seeing high CPU in CICS transactions or in CICS region not attributed to any CICS transaction, then that is likely to be a separate issue not necessarily related to IRLM activity. A trace would tell :)
