perf script: Add field option 'flags' to print sample flags
Instruction tracing will typically have access to information about the instruction being executed for a particular ip sample. Some of that information will be available in the 'flags' member of struct perf_sample. With the addition of transactions events synthesis to Instruction Tracing options, there is a need to be able easily to see the flags because they show whether the ip is at the start, commit or abort of a tranasaction. Consequently add an option to display the flags. The flags are "bcrosyiABEx" which stand for branch, call, return, conditional, system, asynchronous, interrupt, transaction abort, trace begin, trace end, and in transaction, respectively. Example using Intel PT: perf script -fip,time,event,sym,addr,flags ... 1288.721584105: branches:u: bo 401146 main => 401152 main 1288.721584105: transactions: x 0 401164 main 1288.721584105: branches:u: bx 40117c main => 40119b main 1288.721584105: branches:u: box 4011a4 main => 40117e main 1288.721584105: branches:u: bcx 401187 main => 401094 g ... 1288.721591645: branches:u: bx 4010c4 g => 4010cb g 1288.721591645: branches:u: brx 4010cc g => 401189 main 1288.721591645: transactions: 0 4011a6 main 1288.721593199: branches:u: b 4011a9 main => 4011af main 1288.721593199: branches:u: bo 4011bc main => 40113e main 1288.721593199: branches:u: b 401150 main => 40115a main 1288.721593199: transactions: x 0 401164 main 1288.721593199: branches:u: bx 40117c main => 40119b main 1288.721593199: branches:u: box 4011a4 main => 40117e main 1288.721593199: branches:u: bcx 401187 main => 40105e f ... 1288.722284747: branches:u: brx 401093 f => 401189 main 1288.722284747: branches:u: box 4011a4 main => 40117e main 1288.722284747: branches:u: bcx 401187 main => 40105e f 1288.722285883: transactions: bA 0 401071 f 1288.722285883: branches:u: bA 401071 f => 40116a main 1288.722285883: branches:u: bE 40116a main => 0 [unknown] 1288.722297174: branches:u: bB 0 [unknown] => 40116a main ...
