* Introduce warmup phase to BenchmarkRunner (#1130) In order to account for caching effects in user benchmarks introduce a new command line option "--benchmark_min_warmup_time" which allows to specify an amount of time for which the benchmark should be run before results are meaningful. * Adapt review suggestions regarding introduction of warmup phase (#1130) * Fix BM_CHECK call in MinWarmUpTime (#1130) * Fix comment on requirements of MinWarmUpTime (#1130) * Add basic description of warmup phase mechanism to user guide (#1130)
