            Bug ID: 44919
           Summary: Assertion `!isa<CXXConstructorDecl>(D) && "Use other
                    ctor with ctor decls!"' failed.

This assertion is failing for me at head with this reduced repro (using a debug
build of clang):

$ cat repro.cc 
template <typename>
class b {
  __attribute__((target("avx"))) void c();
};
class B {
 public:
  __attribute__((target("avx"))) __attribute__((always_inline)) B();
};
template <typename d>
void b<d>::c() {
  B a;
}
template class b<int>;

$ clang++ -c repro.cc
clang++: llvm-project/clang/include/clang/AST/GlobalDecl.h:45: void
clang::GlobalDecl::Init(const clang::Decl *): Assertion
`!isa<CXXConstructorDecl>(D) && "Use other ctor with ctor decls!"' failed.
