Adrian Hunter 4fbb83c1bf perf intel-pt: Fix missing 'instruction' events with 'q' option

commit a882cc9497 upstream.

FUP packets contain IP information, which makes them also an 'instruction'
event in 'hop' mode i.e. the itrace 'q' option.  That wasn't happening, so
restructure the logic so that FUP events are added along with appropriate
'instruction' and 'branch' events.

Fixes: 7c1b16ba0e ("perf intel-pt: Add support for decoding FUP/TIP only")
