perf report: Support Retire Latency
The Retire Latency field is added in the var3_w of the
PERF_SAMPLE_WEIGHT_STRUCT. The Retire Latency reports pipeline stall of
this instruction compared to the previous instruction in cycles. That's
quite useful to display the information with perf mem report.
The p_stage_cyc for Power is also from the var3_w. Union the p_stage_cyc
and retire_lat to share the code.
Implement X86 specific codes to display the X86 specific header.
Add a new sort key retire_lat for the Retire Latency.
