	* valarith.c (value_binop): Add floating-point BINOP_MIN and
	BINOP_MAX cases.
	For BINOP_EXP, use length and signedness of left operand only for
	result, as for shifts.
	For integral operands to BINOP_EXP, use new integer_pow and
	uinteger_pow functions so as to get full range of results.
	(integer_pow): New function.
	(uinteger_pow): New function.
