How sure are you that it's the IRBuilder doing this? It looks
completely unsound to me in the general case (there's nothing tying
the new globals to their original address), and I've never seen
But it looks very plausibly like what you'd get if you triggered a
completely different part of some decompiler tool to decide that your
accesses are generic enough to be modelled as globals in LLVM.
