Perf memory tool doesn't support AUX trace data so it cannot receive the hardware tracing data. On Arm64, although it doesn't support PMU events for memory load and store, but Arm SPE is a good candidate for memory profiling, the hardware tracer can record memory accessing operations with affiliated information (e.g. physical address and virtual address for accessing, cache levels, TLB walking, latency, etc). To allow "perf mem" tool to support AUX trace, this patch adds the AUX callbacks for session structure; make itrace memory event as default for "perf mem", this tells the AUX trace decoder to synthesize memory samples.
