perf annotate: Use libcapstone to disassemble
Now it can use the capstone library to disassemble the instructions.
Let's use that (if available) for perf annotate to speed up. Currently
it only supports x86 architecture. With this change I can see ~3x speed
up in data type profiling.
But note that capstone cannot give the source file and line number info.
For now, users should use the external objdump for that by specifying
the --objdump option explicitly.
