Subject: perf auxtrace: Add four itrace options

This patch is to add four options to synthesize events which are
described as below:

 'f': synthesize first level cache events
 'm': synthesize last level cache events
 't': synthesize TLB events
 'a': synthesize remote access events

This four options will be used by ARM SPE as their first consumer.
