Pull perf/core improvements and fixes from Arnaldo:

BPF:

  Song Liu:

  - Add support for annotating BPF programs, using the PERF_RECORD_BPF_EVENT
    and PERF_RECORD_KSYMBOL recently added to the kernel and plugging
    binutils's libopcodes disassembly of BPF programs with the existing
    annotation interfaces in 'perf annotate', 'perf report' and 'perf top'
    various output formats (--stdio, --stdio2, --tui).

perf list:

  Andi Kleen:

  - Filter metrics when using substring search.

perf record:

  Andi Kleen:

  - Allow to limit number of reported perf.data files

  - Clarify help for --switch-output.

perf report:

  Andi Kleen

  - Indicate JITed code better.

  - Show all sort keys in help output.

perf script:

  Andi Kleen:

  - Support relative time.

perf stat:

  Andi Kleen:

  - Improve scaling.

General:

  Changbin Du:

    using gcc's ASan and UBSan.
