perf record: Add ability to sample call branches
This patch add a new branch type sampling filter to perf record.
It is named 'call' and maps to PERF_SAMPLE_BRANCH_CALL. It samples
direct call branches only, unlike 'any_call' which includes indirect
calls as well.
$ perf record -j call -e cycles .....
The man page is updated accordingly.
