This code crashes when trying to cast to and from addrspace(5) https://godbolt.org/z/Pa4Kc6Pxo.
```llvm
target triple = "amdgcn-amd-amdhsa"
define amdgpu_kernel void @__omp_offloading_16_1f2c5d17_main_l23(ptr addrspace(5) %0) {
__kmpc_target_init.exit:
unreachable
ompx_gep.exit:
%1 = addrspacecast ptr addrspace(5) %0 to ptr
%2 = addrspacecast ptr %1 to ptr addrspace(5)
unreachable
}
```
This hits the following assertion:
```
opt: /root/llvm-project/llvm/lib/Support/APInt.cpp:907: llvm::APInt llvm::APInt::trunc(unsigned int) const: Assertion `width <= BitWidth && "Invalid APInt Truncate request"' failed.
```
