    perf util: Create branch.c/.h for common branch functions · 992c7e92
    Jin Yao authored
    Create new util/branch.c and util/branch.h to contain the common branch
    functions. Such as:
    
    branch_type_count(): Count the numbers of branch types
    branch_type_name() : Return the name of branch type
    branch_type_stat_display(): Display branch type statistics info
    branch_type_str(): Construct the branch type string.
    
    The branch type is saved in branch_flags.
    
    Change log:
    
    v8: Change PERF_BR_NONE to PERF_BR_UNKNOWN.
    
    v7: Since the common branch type name is changed (e.g. JCC->COND),
        this patch is performed the modification accordingly.
    
    v6: Move that multiline conditional code inside {} brackets.
        Move branch_type_stat_display() from builtin-report.c to
          branch.c.
        Move branch_type_str() from callchain.c to branch.c.
    
    v5: It's a new patch in v5 patch series.

    [ Don't use 'index' and 'stat' as names for variables, it shadows global decls in older distros ]
