[Dylan Li via Phabricator via libc-commits]

  #include "include/string.h"
  
  int main(void) {
    for (unsigned long i = 0; i < 50000000000; ++i) strcmp("hello", "world");
    return 0;
  }

I compiled this with clang 15.0.7 on my x64 Arch Linux machine with an Intel i7-12700H without optimizations. I ran it five times with the patch and five time without it and timed it with the `time` command. On average it ran for 12.8618 seconds with the patch and 12.8766 seconds without for me.
