perf stat: Use counts rather than saved_value

Browse Source 
Switch the hard coded metrics to use the aggregate value rather than
from saved_value. When computing a metric like IPC the aggregate count
comes from instructions then cycles is looked up and if present IPC
computed. Rather than lookup from the saved_value rbtree, search the
counter's evlist for the desired counter.

A new helper evsel__stat_type is used to both quickly find a metric
function and to identify when a counter is the one being sought. So
that both total and miss counts can be sought, the stat_type enum is
expanded. The ratio functions are rewritten to share a common helper
with the ratios being directly passed rather than computed from an
enum value.
