perf: add new PERF_SAMPLE_BRANCH_IND_JUMP branch sample type
This patch adds a new branch_sample_type flag to enable
filtering branch sampling to indirect jumps. The support
is subject to hardware or kernel software support on each
architecture.
Filtering on indirect jump is useful to study the targets
of the jump.
