perf trace: Do not accept --no-syscalls together with -e (2016-04-13 10:11:52 -0300)

perf/core improvements and fixes:
User visible:
- Print callchains asked for events requested via 'perf trace --event' too:

- Allow requesting that some CPUs or PIDs be highlighted in 'perf sched map' (Jiri Olsa)
- Compact 'perf sched map' to show just CPUs with activity, improving the output
in high core count systems (Jiri Olsa)
- Fix segfault with 'perf trace --no-syscalls -e syscall-names' by bailing out
such request, doesn't make sense to ask for no syscalls and then specify which
ones should be printed (Arnaldo Carvalho de Melo)
