Since we can (and do) change comm strings during the collection phase, we cannot actually sort on them to build the histogram. Therefore add an (optional) third sorting phase to collapse the histrogram. Comm sorting now builds the histrogram on threads and then in the collapse phase collects all threads with the same comm. This collapsed histogram is then reversed and sorted on events.

When using interrupting counters and limited (non-interrupting) counters at the same time, it's possible that we get an interrupt in write_mmcr0() after writing MMCR0 but before we have set up the counters using limited PMCs. What happens then is that we get into perf_counter_interrupt() with counter->hw.idx = 0 for the limited counters, leading to the "oops trying to read PMC0" error message being printed. This fixes the problem by making perf_counter_interrupt() robust against counter->hw.idx being zero (the counter is just ignored in that case) and also by changing write_mmcr0() to write MMCR0 initially with the counter overflow interrupt enable bits masked (set to 0). If the MMCR0 value requested by the caller has either of those bits set, we write MMCR0 again with the requested value of those bits after setting up the limited counters properly.

Commit ef923214 ("perf_counter: powerpc: use u64 for event codes internally") introduced a bug where the return value from function find_alternative_bdecode gets put into a u64 variable and later tested to see if it is < 0. The effect is that we get extra, bogus event code alternatives on POWER5 and POWER5+, leading to error messages such as "oops compute_mmcr failed" being printed and counters not counting properly. This fixes it by using s64 for the return type of find_alternative_bdecode and for the local variable that the caller puts the value in. It also makes the event argument a u64 on POWER5+ for consistency.
