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 typeinfo9;

typedef int int_t = 42;

void main()
{
    auto i = typeid(int_t).init;
    assert(i.length == int_t.sizeof);
    assert(*cast(int_t*)i.ptr == 42);
}
