[RFC 0/3] perf tool: Add new event group management

[Jiri Olsa]

hi,
adding support for creating event groups based on the way they
are specified on the command line. Also attaching several fixies
to current code.

attached patches:
 1/3 perf, tool: Fix various casting issues for 32 bits
 2/3 perf, tool: Fix modifier to be applied on correct events
 3/3 perf, tool: Add new event group management

I added automated tests and run some record and stats tests
based on the examples (attached in the 3/3 changelog), and
so far so good..

thanks for comments,
jirka
