Kevin Svetlitski 6841110bd6 Make edata_cmp_summary_comp 30% faster ... `edata_cmp_summary_comp` is one of the very hottest functions, taking up 3% of all time spent inside Jemalloc. I noticed that all existing callsites rely only on the sign of the value returned by this function, so I came up with this equivalent branchless implementation which preserves this property. After empirical measurement, I have found that this implementation is 30% faster, therefore representing a 1% speed-up to the allocator as a whole. At @interwq's suggestion, I've applied the same optimization to `edata_esnead_comp` in case this function becomes hotter in the future.		2023-05-04 09:59:17 -07:00
