Add fault injection of starting warps with random variations (#1593)

* Add fault injection of starting warps with random variations

This is done by inserting randomly delays after __syncthreads().
The feature can be turned off by FAULT_INJECTION=OFF in cmake.

* Remove manually introduced bug for demo purpose

* Use only one thread per warp for checking wall clock
