How important is it to support asyncmarks with the buffer load instructions?
The cleanest way that I can see to eliminate the Aux/CPol bit is to create new
async variants of the intrinsics and set an MMO when lowering them. I would
very strongly prefer to have just one such intrinsic:
```@llvm.amdgcn.global.load.async.lds```
This corresponds to an existing intrinsic without the `.async` in it, and it
can work without an autoupgrade. I am not particularly keen on using
AutoUpgrade just to add a default operand to an existing intrinsic ... that
seems to be a misuse of that facility, and opens the door for any backend to
just redefine intrinsics whenever convenient.
