c++: template template parm pack expansion [PR100372]

Here we have a pack expansion of a template template parameter pack, of
which the pattern is a TEMPLATE_DECL, which strip_typedefs doesn't want to
see.

PR c++/100372

gcc/cp/ChangeLog:

* tree.c (strip_typedefs): Only look at the pattern of a
TYPE_PACK_EXPANSION if it's a type.

gcc/testsuite/ChangeLog:

* g++.dg/cpp0x/alias-decl-ttp1.C: New test.
