c++: ICE in build_deduction_guide for invalid template [PR105760]
We currently ICE upon the following invalid snippet because we fail to
properly handle tsubst_arg_types returning error_mark_node in
build_deduction_guide.
== cut ==
template<class... Ts, class>
struct A { A(Ts...); };
A a;
== cut ==
This patch fixes this, and has been successfully tested on x86_64-pc-linux-gnu.
PR c++/105760

* pt.cc (build_deduction_guide): Check for error_mark_node
result from tsubst_arg_types.

* g++.dg/parse/error66.C: New test.
