 into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

New features:

  - Allow passing C language eBPF scriptlets via --event in all tools,
    so that it gets built using clang and then pass it to the kernel via
    sys_bpf(). (Wang Nan)

  - Wire up the loaded ebpf object file with associated kprobes, so that
    it can determine if the kprobes will be filtered or not. (Wang Nan)

User visible changes:

  - Add cmd string table to decode sys_bpf first arg in 'trace'. (Arnaldo Carvalho de Melo)

  - Enable printing of branch stack in 'perf script'. (Stephane Eranian)

  - Pass the right file with debug info to libunwind. (Rabin Vincent)

Build Fixes:

  - Make sure fixdep is built before libbpf, fixing a race. (Jiri Olsa)

  - Fix libiberty feature detection. (Rabin Vincent)
