Works with LLVM17, using `--print-after-all` confirms that the [passes done are different](https://github.com/ldc-developers/ldc/pull/4604#issuecomment-2028019258)
```
$llc ./addrspace_new_ocl220_64.ll
Assertion failed: ((MI->getOpcode() == SPIRV::OpVariable && i == 3) || Reg2Entry.count(RegOp)), function buildDepsGraph, file SPIRVDuplicatesTracker.cpp, line 59.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
