igt/gem_exec_latency: Initial sketch for measuring execbuf cost in GPU cycles
Similar to benchmarks/gem_latency, but looking more at the dispatch cost
rather than wakeup cost, and looking for inter-engine costs. Still
probably better as a perf test.
ivb over the years:
IGT-Version: 1.16-gebee919 (x86_64) (Linux: 3.10-3-amd64 x86_64)
render: dispatch latency: 50.90, execution latency: 57.29 (target 4.64)
bsd: dispatch latency: 41.45, execution latency: 41.43 (target 4.75)
blt: dispatch latency: 41.02, execution latency: 41.00 (target 4.99)
IGT-Version: 1.16-gebee919 (x86_64) (Linux: 4.8.0-rc5+ x86_64)
render: dispatch latency: 12.61, execution latency: 15.44 (target 1.71)
bsd: dispatch latency: 12.08, execution latency: 12.07 (target 1.80)
blt: dispatch latency: 12.59, execution latency: 12.58 (target 1.85)
