Dominik Inführ 80caf2cf53 [heap] Reduce size of possibly empty buckets ... Before this CL a byte was used per bucket to store whether the bucket is possibly empty or not. This CL changes this such that each bucket only needs a single bit. PossiblyEmptyBuckets is now a word in the page header. If more bits are needed than fit into a single word, an external bitmap is allocated using AlignedAlloc. Storing this on the page header, allows to remove initial_buckets from the SlotSet. The SlotSet allocation is then again a power-of-2 in release mode.
