perf sort: Fix the 'p_stage_cyc' sort key behavior
andle 'p_stage_cyc' (for pipeline stage cycles) sort key with the same
rationale as for the 'weight' and 'local_weight', see the fix in this
series for a full explanation.
Not sure it also needs the local and global variants.
But I couldn't test it actually because I don't have the machine.
