It can be useful to specify branch type state per event, for example if we want to collect both software trace points and last branch PMU events in a single collection. Currently this doesn't work because the software trace point errors out with -b. There was already a branch-type parameter to configure branch sample types per event in the parser, but it was stubbed out. This patch implements the necessary plumbing to actually enable it. Now: $ perf record -e sched:sched_switch,cpu/cpu-cycles,branch_type=any/ ... works.
