jens 584ac47a8a - Bugfix: register bypass with same target register, used for unaligned loads (LWL, LWR), was incorrect. 
Newlib's memcpy() (MIPS-optimized) uses this for unaligned copy.
  Consectutive load instructions without nops using same target register (which is legal) like
   lw $1, 0(mem)
   lwl $1, 1(mem)
  or
   lwl $1, 0(mem)
   lwr $1, 1(mem)
  or similar, lead to incorrect result. Now it's fixed.
