natClass.cc (getMethod): Compute offset relative to klass's methods table, not this's table.

* java/lang/natClass.cc (getMethod): Compute offset relative to
	`klass's methods table, not `this's table.

	* java/lang/reflect/natMethod.cc (_Jv_CallNonvirtualMethodA):
	In unwrapping/widening case, check whether `k' is null, not
	whether it is primitive.  Initialize `num' from `argelts', not
	`paramelts'.  Correct create and pass arguments to ffi_call.
	Don't let presence of `this' argument affect index used to look in
	argument arrays.
	(COPY): Set appropriate element in `values' vector.
