The NVPTX backend currently crashes when trying to compile this test https://github.com/llvm/llvm-project/blob/main/libc/test/src/__support/uint_test.cpp. I have reduced it down to the following LLVM-IR, or in https://godbolt.org/z/TEbxMz5q1.
```llvm
target triple = "nvptx64-nvidia-cuda"
%"struct.BigInt" = type { %"struct.arr" }
%"struct.arr" = type { [2 x i128] }
define void @foo() {
entry:
%call6 = call %"struct.BigInt" null(ptr null, i64 0)
ret void
}
```
This currently crashes in the backend, while other targets seem to handle it fine without crashing.
