Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

. Fix the --stdio2/TUI annotate output to include group details,
  be it for a recorded '{a,b,f}' explicit event group or when
  forcing group display using 'perf report --group' for a set of
  events not recorded as a group (Arnaldo Carvalho de Melo)

. Fix display artifacts in the ui browser (base class for the
  annotate and main report/top TUI browser) related to the extra
  title lines work (Arnaldo Carvalho de Melo)

. perf auxtrace refactorings, leftovers from a previously partially
  processed patchset (Adrian Hunter)

. Fix the builtin clang build (Sandipan Das, Arnaldo Carvalho de Melo)

- Synchronize i915_drm.h, silencing a perf build warning and
  in the process automagically adding support for a new ioctl
  command (Arnaldo Carvalho de Melo)
