perf tools: Add the bash completion for listing subsubcommands of perf timechart
The bash completion does not support listing subsubcommands for 'perf timechart <TAB>', so fix it. Example: Before this patch: $ perf timechart <TAB> $ As shown above, the subsubcommands of perf timechart does not come out. After this patch: $ perf timechart <TAB> record As shown above, the subsubcommands of perf timechart can come out now.
