Am I right that you mean to change the semantic of the addrspace number in a description string for all targets?

At the moment it's finally checked in `ASTContext::getAddrSpaceQualType` that `LangAS` is equal addrspace returned by `QualType`.
And for addrspace "2" specified in description, this `QualType` is "__attribute__((address_space(3))) float". And returns "11" since it's target addrspace, defined in `LangAS` after `FirstTargetAddressSpace`.
So `ASTContext::getAddrSpaceQualType` goes through check `CanT.getAddressSpace() == AddressSpace` and then hits assertions that the parameter already has addrspace specified.
