perf report: Filter to parent set by default
...
Make it easier to use parent filtering - default to a filtered
output. Also add the parent column so that we get collapsing but
dont display it by default.
add --no-exclude-other to override this.

perf_counter: tools: Makefile tweaks for 64-bit powerpc
...
On 64-bit powerpc, perf needs to be built as a 64-bit executable.
This arranges to add the -m64 flag to CFLAGS if we are running on
a 64-bit machine, indicated by the result of uname -m ending in "64".
This means that we'll use -m64 on x86_64 machines as well.

If -vv (very verbose) is specified, print out raw data
in the following format:
$ perf stat -vv -r 3 ./loop_1b_instructions

perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/
...
Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.
