Metal.jl supports atomics through special AIR intrinsics. We should explore whether it's possible to instead lower LLVM atomics to these AIR intrinsics, so that we can just use UnsafeAtomicsLLVM.jl.

    Done in #942 and #943: LLVM atomics are lowered to AIR atomic intrinsics, and unsupported ones are reported as invalid IR.
