This macro protects x86_64-specific code, and a subsequent commit will introduce AArch64-specific versions of that code. To prevent confusion, let's rename it to clearly indicate that it's for x86_64. We should likely move this code to its own file (perhaps merging it with the AVX-512 popcount code), but that is left as a future exercise.
