[PATCH V6 1/4] perf: Add new conditional branch filter PERF_SAMPLE_BRANCH_COND
This patch introduces new branch filter PERF_SAMPLE_BRANCH_COND which
will extend the existing perf ABI. This will filter branches which are
conditional. Various architectures can provide this functionality either
with HW filtering support (if present) or with SW filtering of captured
branch instructions.
