C certainly can do SIMD just as well as assembly (via intrinsics). It does not allow high-level code to be compiled to SIMD, but there is no known way to compile high-level general-purpose code to SIMD. Finding such a method is an Open Research Problem AFAIK (of course, solving it would be Very Welcome).
