I feel like updating this with a CAS loop is a good middle-ground https://github.com/llvm/llvm-project/pull/96692. This also lets the GPU implementation actually work, since previously I couldn't statically initialize it to 1. Though, it's not like CAS loops are cheap, but I didn't want to use actual locks since they're a PITA to make work on the GPU (see the RPC implementation).
