From 56dcaeec46dd53e271d6f201d2028996bf19f9dd Mon Sep 17 00:00:00 2001 From: Santiago Aboy Solanes Date: Fri, 22 Mar 2024 10:45:15 +0000 Subject: Remove extra uses of ClearAllBits ArenaBitVector creation guarantees it starts empty. Add a debug check to make sure this assumption doesn't change. Note that ArenaAllocator guarantees zero-initialized memory but ScopedArenaAllocators do not. This is fine either way since the BitVector constructor calls ClearAllBits.
