Instruction sample types are enabled in the default itrace options in perf, but this never applied to SPE because the default nanoseconds period isn't supported. This meant that instructions ended up being opt-in by the user only when they requested an instruction based period. Change the default period type to instructions so that instruction samples are generated by default. This can overridden by specifying any --itrace option. This solves a common complaint from users that the unfiltered SPE samples appear to be missing, and only the samples that have memory flags set appear in the various memory groups.
