perf script: Support insn and insnlen
When looking at Intel PT traces with perf script it is useful to have
some indication of the instruction. Dump the instruction bytes and
instruction length, which can be used for simple pattern analysis in
scripts.
% perf record -e intel_pt// foo
% perf script --itrace=i0ns -F ip,insn,insnlen
