[pushed] c++: Call tsubst_pack_expansion from tsubst.

[pushed] c++: Call tsubst_pack_expansion from tsubst.

[Jason Merrill]

This was unnecessary (and incomplete) code duplication.

Tested x86_64-pc-linux-gnu, applying to trunk.

gcc/cp/ChangeLog:

	* pt.c (tsubst): Replace *_ARGUMENT_PACK code with
	a call to tsubst_argument_pack.
