Initialize LLVM target and asmprinter for the native and extra targets. Uses some CMake hackery to get the native LLVM target name, since it only provides a conveniance function for initializing the native target and not the native asmprinter.

module typeinfo7;
extern(C) int printf(char*, ...);
int func(long)
{
    return 0;
}

void main()
{
    auto ti = typeid(typeof(func));
    auto s = ti.toString;
    printf("%.*s\n", s.length, s.ptr);
    assert(s == "int()");
}
