Fix an issue that illegal percent was accepted previously (e.g. 1abc%) perf util: Improve error checking for time percent input 3. Omit the slice index if possible. For example, perf report --stdio --time 10%/1 is equivalent to perf report --stdio --time 10% perf util: Support no index time percent slice 4. Add indication of time slices in perf report header. perf report: Add an indication of what time slices are used 5.
