Yan, Zheng e18bf52642 perf/x86/intel: Allocate space for storing LBR stack ...

When the LBR call stack is enabled, it is necessary to save/restore
the LBR stack on context switch. We can use pmu specific data to
store LBR stack when task is scheduled out. This patch adds code
that allocates the pmu specific data.
