It's also part of `addAddressSpaceInferencePasses`, but since these passes are only added if `getOptLevel() != CodeGenOptLevel::None`, I also added it in the else branch of the check. 

I am wondering if `InferAddressSpaces` should also be run to remove the address space casts. Or maybe a simplified version of it.
