[PATCH v2 0/7] perf tools: Add support for some spe events and precise ip

[James Clark <james.clark@arm.com>]

After the commit ffd3d18c20b8 ("perf tools: Add ARM Statistical
Profiling Extensions (SPE) support") was merged, "perf record" and
"perf report --dump-raw-trace" are supported. However, the
raw data that is dumped cannot be used without parsing.

This patchset is to improve the "perf report" support for SPE, and
further process the data. Currently, support for the three events
of llc-miss, tlb-miss, branch-miss and remote-access is added.

The macro definition was modified under Jeremy's suggestion, and
the "event:pp" approach was used under James' suggestion to achieve
the precise ip of some events on arm64. Currently, only branch-misses
are implemented, and other event support will be added later.

In addition, we also found that when recording large multi-threaded
programs, ctrl + c could not end recording, so it was fixed and two
patches were added.
