A bug was fixed in the IRA (Integrated Register Allocator) conflict building process where a wrong conflict allocno was being used. While the allocno was only used in an assertion, the assertion was always true and thus ineffective. The fix ensures the correct conflicting allocno is used, making the assertion meaningful.
