Fix build for LLVM >= r74640 Some LLVM objects now take a 'Context' to make multi-threaded apps easier. Since we're not multi-threaded it's safe to use llvm::getGlobalContext() which gives us the same behavior as we had before.

module classes11;
extern(C) int printf(char*, ...);

void main()
{
    static class C
    {
        void func()
        {
            printf("Hello world\n");
        }
    }

    scope c = new C;
    c.func();
}
