Subject: [PATCH v1 3/3] perf record: add support for sampling indirect jumps

This patch adds a new branch sampling type support for indirect jumps:

perf record -j ind_jmp .......

It enables analysis of indirect jumps targets. It requires kernel and
possibly hardware support to operate correctly.
