Log message:
	sim: bfin: always do 16bit sign extension with the SEARCH insn
	
	The Blackfin PRM does not cover this case, but the hardware is clear: even
	if the search criteria is not met (and thus a new 16bit value is loaded up
	into the accumulator), the accumulator undergoes 16bit sign extension.  So
	simply reload the low signed 16bits in that case.
