perf tools: Create function to perform multiple time range checking
Previous patch supports the multiple time range. For example, select the first and second 10% time slices. perf report --time 10%/1,10%/2 We need a function to check if a timestamp is in the ranges of [0, 10%) and [10%, 20%]. Note that it includes the last element in [10%, 20%] but it doesn't include the last element in [0, 10%). It's to avoid the overlap. This patch implments a new function perf_time__ranges_skip_sample for this checking. Change log: v4: Let perf_time__ranges_skip_sample be compatible with perf_time__skip_sample when only one time range.
