PR C/71602
* builtins.c (std_canonical_va_list_type): Strictly return non-null for
va_list type only.
* config/i386/i386.c (ix86_canonical_va_list_type): Same.
* gimplify.c (gimplify_va_arg_expr): Handle &va_list.
* c-common.c (build_va_arg): Handle more strict
targetm.canonical_va_list_type.
* c-c++-common/va-arg-va-list-type.c: New test.

Happy to see the _REF nodes disappearing from
std_canonical_va_list_type. If I understand the code correctly its
argument should always be a type node, so handling an _REF node makes no
sense.
OK for the trunk.
