Unlike the previous version
(https://github.com/llvm/llvm-project/pull/114978), this patch also
removes an unnecessary assert that causes Clang to crash when compiling
such tests. (clang/lib/AST/DeclCXX.cpp)
https://lab.llvm.org/buildbot/#/builders/52/builds/4021
```c++
template <class T>
class X {
public:
X() = default;
virtual ~X() = default;
virtual int foo(int x, int y, T &entry) = 0;
void bar() {
struct Y : public X<T> {
Y() : X() {}
int foo(int, int, T &) override {
return 42;
}
};
}
};
```
the assertions:
```c++
llvm-project/clang/lib/AST/DeclCXX.cpp:2508: void clang::CXXMethodDecl::addOverriddenMethod(const CXXMethodDecl *): Assertion `!MD->getParent()->isDependentContext() && "Can't add an overridden method to a class template!"' failed.
```
I believe that this assert is unnecessary and contradicts the logic of
this patch. After its removal, Clang was successfully built using
itself, and all tests passed.
