Make expr_range_in_bb stmt based rather than block based.

prerequisite to moving to a range_query model, make it stmt based.

	* gimple-range-gori.cc (gori_compute::expr_range_at_stmt): Rename
	from expr_range_in_bb and adjust.
	(gori_compute::compute_name_range_op): Adjust.
	(gori_compute::optimize_logical_operands): Adjust.
	(gori_compute::compute_logical_operands_in_chain): Adjust.
	(gori_compute::compute_operand1_range): Adjust.
	(gori_compute::compute_operand2_range): Adjust.
	(ori_compute_cache::cache_stmt): Adjust.
	* gimple-range-gori.h (gori_compute): Rename prototype.
