Temporary hack to let codegen assert or generate poor code in case we are using AVX and no AVX version of the desired intruction is present, this is better for incremental dev (without fallbacks it's easier to spot what's missing). Not sure this is the best hack thought (we can also disable all HasSSE* predicates by dinamically marking them 'false' if AVX is present)
