Use the reproducer from #71593.
Add "-v --save-temps" to the compile line. Get an error:
```
a.out.amdgcn-amd-amdhsa.gfx900.s:100638:27: error: invalid operand (violates constant bus restrictions)
v_writelane_b32 v7, s24, m0
```
Add "-O0" (and no "--save-temps") and get an assertion failure:
```
clang-linker-wrapper: llvm-project/llvm/lib/Target/AMDGPU/AMDGPUResourceUsageAnalysis.cpp:154: virtual bool llvm::AMDGPUResourceUsageAnalysis::runOnModule(llvm::Module&): Assertion `MF && "function must have been generated already"' failed.
```
