Fixes and improvements for perf/core:

- perf_target: abstraction for --uid, --pid, --tid, --cpu, --all-cpus handling,
  eliminating code duplicated in the tools, having constraints that apply to
  all of them, from Namhyung Kim

- Fixes for handling fallback to cpu-clock on PPC, from David Ahern

- Fix for processing events with unknown size, from Jiri Olsa

- Compilation fix on 32-bit, from Jiri Olsa
