[PATCH 1/1] perf: display raw event for mem report

[Dan Schatzberg]

`perf mem record` can be used to capture memory loads/stores using
PEBS counters. `perf mem report -D` can be used to dump the raw
samples (e.g. each sampled memory access). However, it does not output
the raw event (load vs store).

This patch supplements the output of `perf mem report -D` with the
event name.
