jonathan b1032ac9db Substitute Mach 3.0 MK84 mips kernel bcopy() for Sprite bcopy().
Has unrolled loop for aligned-to-aligned copy.

Notes:
  1. this code tuned for DEC 5000/200.  ioasic decstations do more unaligned
     copies.  Better than old non-unrolled loop, but could be improved.

  2. Undoes changes made for MIPS3 with comment implying an r4000 TLB bug.
     We can't reproduce this on 5000/150 (jonathan) or 5000/50 (mhitch).
     Calls to previous  bcopy with a bad address show similar symptoms,
     reporting a trap in bcopy() after bcopy() has returned.  Same thing??
     Needs re-checking on an r4000 with no L2 cache.
