So in my initial implementation, before I submitted it for review, I 
tried making them not be Constants, only to discover that if I did that 
then I couldn't use then as GV initializers.

And it's not preposterous for them to be Constants. Functions are an 
example of a nameable zero-operand non-uniqued constant.

Is there any particular benefit to keeping them out of Constant and 
adding NamedMetadata?
