Rollup merge of #114382 - scottmcm:compare-bytes-intrinsic, r=cjgillot
Add a new `compare_bytes` intrinsic instead of calling `memcmp` directly As discussed in #113435, this lets the backends be the place that can have the "don't call the function if n == 0" logic, if it's needed for the target. (I didn't actually *add* those checks, though, since as I understood it we didn't actually need them on known targets?) Doing this also let me make it `const` (unstable), which I don't think `extern "C" fn memcmp` can be. cc `@RalfJung` `@Amanieu`
