Subject: natField.cc (setAddr): New function.

	* java/lang/reflect/natField.cc (setAddr):  New function.
	Calls getAddr and then checks that the field isn't final.
	(setBoolean. setChar, setByte, setShort, setInt, setLong, setFloat,
	setDouble, set):  Use setAddr instead of getAddr, to check for FINAL.
	(set):  Call setAddr before check that new value has right type,
	to better match specified semantics.
