c++: deducing empty type vs non-type argument pack

Within a template parameter list, a non-type template parameter pack is
represented as a PARM_DECL.  But in a couple of spots where we need to
deduce and create an empty argument pack, we test for TEMPLATE_PARM_INDEX
(within a template parameter list) instead of for PARM_DECL, and so we
end up creating a TYPE_ARGUMENT_PACK even in the non-type case.  This
patch fixes this (seemingly harmless) bug.

gcc/cp/ChangeLog:

	* pt.cc (type_unification_real): Test for PARM_DECL instead
	of TEMPLATE_PARM_INDEX to distinguish a type vs non-type
	template parameter pack.
	(type_targs_deducible_from): Likewise.
