I think I prefer regular memset to __hwasan_memset.
__hwasan variants can be slightly faster because they don't need to check that the address is not a shadow address (from stack tagging), but that is probably not a big deal.
Also the hardware implementation will definitely not have (or need) __hwasan_memset.
