[Beignet] [PATCH 16/21 V3] Backend: Avoid CALC_TIMESTAMP and STORE_PROFILING being scheduled.

[junyan.he at inbox.com]

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

We do not want CALC_TIMESTAMP and STORE_PROFILING to be scheduled
with other instructions, because it will get the wrong timestamps.
