perf/core improvements and fixes:
New features:
- Make -a/--all-cpus be the default target in 'perf record' and 'perf stat',
just like it is with 'perf trace' (Jiri Olsa)
- Introduce -q/--quiet to the 'annotate', 'diff' and 'report', fix up
its behaviour in 'record'. This makes the output more compact by
elliminating headers, leaving just the histogram lines (Namhyung Kim)
Fixes:
- Handle offline/absent CPUs (Jan Stancek)
Infrastructure:
- Filter out -specs=/a/b/c from CC options when building the python
support, allowing that feature to be built with clang (Arnaldo Carvalho de Melo)
- Fix DEBUG=1 build with clang (Arnaldo Carvalho de Melo)
Trivial:
- Fix spelling of 'preempt' in a libtraceevent function name (Steven Rostedt)

perf record: Honor --quiet option properly
It should call perf_quiet_option() to suppress messages.
