Okay, I see the problem. https://github.com/llvm/llvm-project/blob/389679d5f9055bffe8bbd25ae41f084a8d08e0f8/llvm/lib/Target/NVPTX/NVPTXFrameLowering.cpp#L96 is initializing the wrong union member. Previously this didn't matter because they had the same layout.

I'll put up a patch after confirming this...
