    Subject[PATCH 22/57] perf c2c report: Add iaddr dimension key
    Date
    Adding iaddr dimension key support. It displays
    code address (as hex number) responsible for the
    accesses.

    Using c2c wrapper to standard 'symbol_iaddr' object
    to define own header and simple (just address) code
    address output.
