Log message:
	2002-01-03  Dave Brolley  <brolley@redhat.com>
	
	* decode.scm (-distinguishing-bit-population): Compute num-insns, the
	number of insns in the list.  Update the population count function to
	identify and prioritize 3 catgories of useful bits.
	(-population-top-few): Don't consider bits with a population count of
	zero.
	(-build-decode-table-entry): Don't call
	filter-harmlessly-ambiguous-insns.  Filter out non-specialized and
	identical insns at the next tree level.
	* insn.scm (filter-harmlessly-ambiguous-insns): Note in a comment that
	this function is no longer used.
	(filter-non-specialized-ambiguous-insns): New function.
	(filter-identical-ambiguous-insns): New function.
	(find-identical-insn): New function.
	(filter-harmlessly-ambiguous-insns): Removed.
