perf evsel: Assign abbr name for the branch counter events
There could be several branch counter events. If perf tool output the
result via the format "event name + a number", the line could be very
long and hard to read.
An abbreviation is introduced to replace the full event name in the
display. The abbreviation starts from 'A' to 'Z9', which can support
up to 286 events. The same abbreviation will be assigned if the same
events are found in the evlist. The next patch will utilize the
abbreviation name to show the branch counter events in the output.
