Core: Fix a -Wshadow warning in gcc 11 This moves the only direct call to zlib’s crc32() into its own translation unit, but that operation is cold enough that this won’t matter in the slightest. crc32_z() would be more appropriate, but Android has an older zlib version… 2021-05-17 21:17:36 +02:00			`// Copyright 2021 Dolphin Emulator Project`
