[Beignet] [PATCH 04/19] Backend: Add profiling registers to curbe.

[junyan.he at inbox.com]

From: Junyan He <junyan.he at linux.intel.com>

1. 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.
2. Delete the unused laneid string in the specialRegMean.
