Adrian Hunter e1791347b5 perf auxtrace: Fix 'instructions' period of zero ... Instruction tracing options (i.e. --itrace) include an option for sampling instructions at an arbitrary period. e.g. --itrace=i10us means make an 'instructions' sample for every 10us of trace. Currently the logic does not distinguish between a period of zero and no period being specified at all, so it gets treated as the default period which is 100000. That doesn't really make sense. Fix it so that zero period is accepted and treated as meaning "as often as possible". In the case of Intel PT that is the same as a period of 1 and a unit of 'instructions' (i.e. --itrace=i1i).
