        Optimize the generic and x86 memchr.
        * libc/string/memchr.c (memchr) [!__OPTIMIZE_SIZE__]:
        Pre-align pointer so unaligned searches aren't penalized.
        * libc/machine/i386/memchr.S (memchr) [!__OPTIMIZE_SIZE__]: Word
        operations are faster than repnz byte searches.
