definition or non-reference class type.
The crash occurs when there is a template parameter list in a class that
is missing the closing angle bracket followed by a definition of a
struct. For example:
class C0 {
public:
template<typename T, typename T1 = T // missing closing angle bracket
struct S0 {};
C0() : m(new S0<int>) {}
S0<int> *m;
};
This happens because the parsed struct is added to the scope of the
enclosing class without having its access specifier set, which results
in an assertion failure in SemaAccess.cpp later.
This commit fixes the crash by adding the parsed struct to the enclosing
file scope and marking structs as invalid if they are defined in
template parameter lists.

This patch fixes PR16677. The latter represents the case when due to
misprinted character class definition occurs in the scope of template
arguments. Base class of this class depends on the template parameter in the
same scope and cannot be resolved, it causes crash. Right behavior is to
make semantic processing even if the definition is wrong, as the code
that emits appropriate message is called after the processing.
