Backend: Add profiling registers to curbe.
Add five timestamp reigsters and one pointer register
into curbe. The five timestamp reigsters will hold
all the infomation of profiling timestamps, includes
20 uint timestamps for each point, 1 ulong prolog holding
the start time and and 1 ulong epilog holding the
end time of that kernel. The pointer reigster will hold
the log buffer address.
