Replace uses of determine_value_range with range_of_expr.

The expression evaluator changes to the range_query API provide
everything determine_value_range does.  This patch replaces all uses
with calls into the range_query API.

gcc/ChangeLog:

	* calls.c (get_size_range): Use range_of_expr instead of
	determine_value_range.
	* tree-affine.c (expr_to_aff_combination): Same.
	* tree-data-ref.c (split_constant_offset): Same.
	* tree-vrp.c (determine_value_range_1): Remove.
	(determine_value_range): Remove.
	* tree-vrp.h (determine_value_range): Remove.
