    kernel and world - Replace bcmp/bcopy/bzero/memcmp/memcpy/memmove/memset
    
    * Replace bcmp/bcopy/bzero/memcmp/memcpy/memmove/memset with mjg's
      code, with some minor adjustments.
    
    * mjg's code has been given its own header file,
      <machine/asm_mjgmacros.h>
    
    * Also replaces copyin and copyout.
    
    * Around a 1.7% improvement in bulk-build performance.
