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.
