values to program into branch_sample_type when PERF_SAMPLE_BRANCH is set

If the user does not pass priv level information via branch_sample_type the kernel uses the event’s priv level. Branch and event priv levels do not have to match. Branch priv level is checked for permissions.

The branch types can be combined, however BRANCH_ANY covers all types of branches and therefore it supersedes all the other types. user branches
