Well, it wouldn't be better than a literal equivalent to those intriniscs,
if that's what we're talking about. By which I mean, like, say how in
Clang/GCC (or languages such as Rust that use LLVM), if you do _mm_loadl_pd
or whatever, that translates not to a function call but directly to the
"inlined" assembler instructions (at least in release builds.)
