For a compiler intrinsic, if it is used in a non-call context, e.g. as a function pointer, currently it requires fallback implementation (e.g. assembly code for atomic operations), otherwise it will result in a build failure. The fallback implementation needs to be maintained and tested, albeit rarely used in practice. Also, for SIMD, we're currently adding a large number of compiler intrinsics without providing fallback implementations (we might in the future). As methods, it is not unlikely that they are used in a non-call context, e.g. referenced from the type descriptor. This CL lets the compiler generate the function body for bodyless intrinsics. The compiler already recognizes a call to the function as an intrinsic and can directly generate code for it. So we just fill in the body with a call to the same function.
