Try PAPI: http://icl.cs.utk.edu/papi/
It offers you all information that the CPU has to offer for this. It depends
on you how to gather them.
However, for an instruction-level histogramm, a simulator will probaby be more
useful. And you should think about if you *really* need this - if the
information you get is worth the effort.
