Allow usage of huge maintenance_work_mem for GIN build.
Currently, in-memory posting list during GIN build process is limited 1GB
because of using repalloc. The patch replaces call of repalloc to repalloc_huge.
It increases limit of posting list from 180 millions
(1GB / sizeof(ItemPointerData)) to 4 billions limited by maxcount/count fields
in GinEntryAccumulator and subsequent calls. Check added.
Also, fix accounting of allocatedMemory during build to prevent integer
overflow with maintenance_work_mem > 4GB.
