What Eric mentioned (though I'm not sure about the "tidy up
attributes" thing - I'm mostly OK with simple compilations of C++ code
with Clang & taking whatever it produces from minimal code - adding
extra flags to simplify the IR... I'm on the fence about that)

But could you make sure not to hardcode metadata node numbers, but
