I think this is fine.  Most of the patch is changing calls to `getTargetAddressSpace` to be internal to IRGen, which, as mentioned, I think is the right move.

I do think that if we're going to support multiple program address spaces (which seems to be a goal) that we'll eventually want an AST-level concept of the default program address space, but perpetuating the use of target ASes at the AST level isn't the right way to approach that, so this is still the right first step.
