Add arch specific arch_evsel__set_sample_weight() to set the new sample type for powerpc. Add arch specific arch_perf_parse_sample_weight() to store the sample->weight values depending on the sample type applied. if the new sample type (PERF_SAMPLE_WEIGHT_STRUCT) is applied, store only the lower 32 bits to sample->weight. If sample type is 'PERF_SAMPLE_WEIGHT', store the full 64-bit to sample->weight.
