Fix overflow in bsearch_arg() with more than INT_MAX elements

This was introduced in commitbfa2cee, which replaced the oldbsearch_cmp() function we had in extended_stats.c with the currentimplementation. The original discussion or commit message ofbfa2cee didn't mention where the new implementation came from, butbased on some googling, I'm guessing *BSD or libiberty, all of whichshare this same code, with or without this fix.Author: Ranier VilelaReviewed-by: Nathan BossartBackpatch-through: 14Discussion:https://www.postgresql.org/message-id/CAEudQAp34o_8u6sGSVraLwuMv9F7T9hyHpePXHmRaxR2Aboi%2Bw%40mail.gmail.com
