Add mapfile.csv and power8.json files for the Power8 processor.
Changelog[v3]
- [Namhyung Kim] Remove text from PublicDescription fields if it is
identical to or prefix of BriefDescription.
Changelog[v2]
- [Andi Kleen] Replace the vendor-family-model,version fields with
cpuid,version fields (to simplify mapfile)
- Reuse the JSON files when possible (i.e multiple cpuids can refer
to the same JSON file) - so drop the 004d0100.json and use
power8.json in multiple entries in mapfile.
- Add few more Power8 PVRs to mapfile
Changelog[v21]
- Group events into per topic per cpu model.

When building on Ubuntu 16.04, I get the following error:
Makefile:49: *** the openjdk development package appears to me missing, install and try again. Stop.
The problem is that update-java-alternatives has multiple spaces between

This patch helps with Sukadev's vendor event tree where such events can happen.
>From Andi Kleen:
Any event including a .c/.o/.bpf currently triggers BPF compilation or loading
and then an error. This can happen for some Intel vendor events, which cannot
be used.
This patch fixes this problem by forbidding BPF file patch containing '{', '}'
and ',', make sure flex consumes the leading '{', instead of matching it using
a BPF file path.
Tested result:
$ perf stat -e '{unc_p_clockticks,unc_p_power_state_occupancy.cores_c0}' -a -I 1000
invalid or unsupported event: '{unc_p_clockticks,unc_p_power_state_occupancy.cores_c0}'

Unlike normal report view, hierarchy mode needs to keep its own entry

The MTC packet provides a 8-bit slice of CTC which is related to TSC by
the TMA packet, however the TMA packet only provides the lower 16 bits
of CTC. If mtc_shift > 8 then some of the MTC bits are not in the CTC
provided by the TMA packet. Fix-up the last_mtc calculated from the TMA
packet by copying the missing bits from the current MTC assuming the
least difference between the two, and that the current MTC comes after
last_mtc.

In cycle-accurate mode, timestamps can be calculated from CYC packets.
The decoder also estimates timestamps based on the number of
instructions since the last timestamp. For that to work in
cycle-accurate mode, the instruction count needs to be reset to zero
when a timestamp is calculated from a CYC packet, but that wasn't
happening, so fix it.

The JSON event lists use a different encoding for fixed counters than
perf for instructions and cycles (ref-cycles is ok)
This lead to some common events like inst_retired.any or
cpu_clk_unhalted.thread not counting, when specified with their JSON
name.
Special case these events in the jevents conversion process. I prefer
to not touch the JSON files for this, as it's intended that standard
JSON files can be just dropped into the perf build without changes.

Make alias matching the events parser case-insensitive. This is useful
with the JSON events. perf uses lower case events, but the CPU manuals
generally use upper case event names. The JSON files use lower case by
default too. But if we search case insensitively then users can
cut-n-paste the upper case event names.
So the following works:
% perf stat -e BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL true

To work with existing mapfiles, assume that the first line in
'mapfile.csv' is a header line and skip over it.

Implement the code to match CPU types to mapfile types for x86 based on
CPUID. This extends an existing similar function, but changes it to use
the x86 mapfile cpu description. This allows to resolve event lists
generated by jevents.

Implement code that returns the generic CPU ID string for Powerpc. This
will be used to identify the specific table of PMU events to
parse/compare user specified events against.
