If a global initializer has a non-trivial constructor or destructor, we never want to defer generation of it, even if it is declared static.

With this change we're finally able to compile and run the (infamous)

#include <string>
#include <iostream>

int main(int argc, char **argv) {
  std::cout << "Hello, World" << std::endl;
}

$ clang hello.cpp -lstdc++ -o hello
$ ./hello 
Hello, World

additional header file or library dependencies. Convert MachineFunctionPass
and CodeGenLICM to make use of this.

with incomplete type as an invalid declaration.

more tests to ensure that explicit specializations of member function
templates prevent instantiation.

instantiated or specialized. 

Make sure that we don't try to instantiate an explicitly-specialized
member class of a class template, when that explicit specialization
was a declaration rather than a definition.

track of the kind of specialization or instantiation. Also, check the
scope of the specialization and ensure that a specialization
declaration without an initializer is not a definition.

end up implicitly instantiating functions that had explicit

function of a class template was implicitly instantiated, explicitly
instantiated (declaration or definition), or explicitly
specialized. The same MemberSpecializationInfo structure will be used
for static data members and member classes as well.
