More fallout from the variadic templates on mainline:
===========================================================
template <typename... T> struct A
{
A(T* p) { (A<T...>*)(p); }
};
A<int> a(0);
===========================================================
bug.cc:3: error: parameter packs not expanded with `...':
bug.cc:3: note: 'T'
bug.cc:3: error: parameter packs not expanded with `...':
bug.cc:3: note: 'T'
bug.cc: In constructor 'A<T>::A(T*) [with T = int]':
bug.cc:6: instantiated from here
bug.cc:3: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have template_type_parm in lookup_base, at
cp/search.c:213
Please submit a full bug report, [etc.]
Similar to PR31436 as this is also invalid use of a parameter pack
in a function argument and triggers an ICE in a lookup_* function.

* error.c (dump_type): Dump TYPE_ARGUMENT_PACK nodes.
* cp-tree.h (check_for_bare_parameter_packs): Returns bool.
* pt.c (check_for_bare_parameter_packs): Return bool indicated
whether everything was okay. Fix indentation.
(push_template_decl_real): Check for bare parameter packs in
function parameters; where errors occur, mark the parameter types
with ERROR_MARK_NODEs to avert ICEs.
(coerce_template_parameter_pack): New.
(coerce_template_parms): Moved parameter pack coercion into
coerce_template_parameter_pack, and permit it anywhere in the
template parameter list (not just at the end). Parameter and
argument indices can vary (somewhat) separately now, so add
PARM_IDX and ARG_IDX.
(fn_type_unification): Don't set an argument pack as incomplete if
no argument pack was deduced.
(type_unification_real): If a type parameter is a parameter pack
and has not otherwise been deduced, it will be deduced to an empty
parameter pack.
(more_specialized_fn): Use the actual lengths of the argument
lists when comparing against expansions.
* semantics.c (finish_member_declaration): If a field's type has
bare parameter packs, error and set its type to ERROR_MARK_NODE.
