      Description

        Currently we only print:

        CodeCache:
        nmethod dependency checking time 0.037552
         #944 live = 3681K (hdr 4%, loc 2%, code 74%, stub 1%, [oops 0%, data 0%, pcs 5%])
         #92 dead = 247K (hdr 7%, loc 6%, code 46%, stub 3%, [oops 0%, data 0%, pcs 12%])

        We should enhance the machinery to:

        - print live and dead method information for all tiers
        - print absolute numbers instead of percentages
        - print size of template interpreter code
        - print size of stub code (maybe number of stubs?)
        - maybe print percentage of code cache memory used for tiers/interpreter/stubs
