In order to open perf events per core, we need to first get the list of
core ids available in the system. So I'm adding a function that does
that by parsing /proc/cpuinfo. That seems to be the simplest and most
portable way to do that.
Besides that, I made a few refactors and renames to reflect better that
the cpu info that we use in lldb-server comes from procfs.
