parentperf record: Add HEADER_BRANCH_STACK tag (diff)
perf report: Auto-detect branch stack sampling mode
This patch enhances perf report to auto-detect when the perf.data file contains samples with branch stacks. That way it is not necessary to use the -b option. To force branch view mode to off, simply use --no-branch-stack.
