* value.h (value_add, value_sub): Remove.

(value_ptradd, value_ptrsub, value_ptrdiff): Add prototypes.
	* valarith.c (value_add, value_sub): Remove.
	(value_ptradd, value_ptrsub, value_ptrdiff): New functions.
	(find_size_for_pointer_math): Add assertion.  Update comment.
	(value_binop): Update comment.

	* eval.c (ptrmath_type_p): New function.
	(evaluate_subexp_standard): Replace value_add and value_sub
	by value_ptradd, value_ptrsub, value_ptrdiff or value_binop.
	Use builtin_type_uint8 instead of builtin_type_char to hold
	the increment for BINOP_{PRE,POST}{IN,DE}CREMENT operations.
	* valarith.c (value_subscript): Replace value_add by
	value_ptradd.  Replace value_sub by value_binop.
	* ada-lang.c (ada_value_ptr_subscript): Likewise.
	(ada_tag_name_2): Replace value_add by value_ptradd.
	(ada_evaluate_subexp): Replace value_add and value_sub by
	value_binop.
	* m2-lang.c (evaluate_subexp_modula2): Replace value_add
	by value_ptradd.
	* gnu-v2-abi.c (gnuv2_virtual_fn_field): Likewise.
	* gnu-v3-abi.c (gnuv3_method_ptr_to_value): Likewise.
