OpenCL 1.2 atomic builtins have relaxed semantics. Always, it is not parameter, it is defined behavior. I want to translate them to atomicrmw instruction and use one of clang intrinsics for this.
I can't use _sync_fetch_*, due to the different semantics. The __atomic_* allow to specify semantics, but min/max is missing in this set.
