* double-int.h (force_fit_type_double): Remove declaration.
	* double-int.c (force_fit_type_double): Move to tree.c.
	* tree.h (force_fit_type_double): Declare.
	* tree.h (force_fit_type_double): Moved from double-int.c. Use
	double_int type for 'cst' argument. Use double_int_fits_to_tree_p and
	double_int_to_tree instead of fit_double_type and build_int_cst_wide.
	* convert.c (convert_to_pointer): Adjust call to
	force_fit_type_double.
	* tree-vrp.c (extract_range_from_assert,
	extract_range_from_unary_expr): Adjust call to force_fit_type_double.
	* fold-const.c: Update comment.
