perf tests clang: Fix function name for clang IR test (2018-04-09 11:13:09 -0300)

----------------------------------------------------------------
perf/urgent fixes:

. 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)

Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support. Where clang is available, it is also used to build
perf with/without libelf.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
