v5:
---
Mainly the v5 patch series are updated according to
comments from Jiri Olsa <jolsa@redhat.com>.

The kernel part doesn't have functional change. It just
solve the merge issue.

In userspace, the functions of branch type counting and
branch type name resolving are moved to the new files:
util/branch.c, util/branch.h.

And refactor the branch info printing code for better
maintenance.

Not changed (or just fix merge issue):
perf/core: Define the common branch type classification
perf/x86/intel: Record branch type
perf record: Create a new option save_type in --branch-filter

New patches:
perf report: Refactor the branch info printing code
perf util: Create branch.c/.h for common branch functions

Changed:
perf report: Show branch type statistics for stdio mode
perf report: Show branch type in callchain entry

v4:
---
1. Describe the major changes in patch description.
Thanks for Peter Zijlstra's reminding.

2. Initialize branch type to 0 in intel_pmu_lbr_read_32 and
intel_pmu_lbr_read_64. Remove the invalid else code in
intel_pmu_lbr_filter.

v3:
---
1. Move the JCC forward/backward and cross page computing from
kernel to userspace.

2. Use lookup table to replace original switch/case processing.

Changed:
perf/core: Define the common branch type classification
perf/x86/intel: Record branch type
perf report: Show branch type statistics for stdio mode
perf report: Show branch type in callchain entry

Not changed:
perf record: Create a new option save_type in --branch-filter

v2:
---
1. Use 4 bits in perf_branch_entry to record branch type.

2. Pull out some common branch types from FAR_BRANCH. Now the branch
types defined in perf_event.h:
