Add preemption_logger benchmark, make target, and fix d82c60c

Benchmark supports:
=> Spinning on-GPU until some number of preemptions have occured
=> Monitoring GPU scheduling by logging preempt and resume times
=> Logging the above as raw GPU, or converted CPU, times
=> Measuring launch overheads

Also imports task_host_utilities.cu from cuda_scheduling_examiner
as of commit 9fc0ca898ef64b82cbc3734c60405723650bc66f. This is
needed for timing logic used in both preemption_logger and
mon_cross_ctx_copies, thus the latter would not compile prior to
this commit.

Also adds a new testbench helper, and a .gitignore for binaries.
