Regarding https://github.com/llvm/llvm-project/pull/162687 : There is an oddie I found with
```
__attribute__((device)) register long global_dev_hreg asm("rsp"); // device-side error
```
This should error out but it doesn't anymore, probably because __attribute__((device)) is now processed after `asm("rsp")`. So some special logic needs to be done.

Or just sort by SourceLocation :)
