I've committed this patch to remove some unused or unnecessary operand 
predicates.  The address-space predicates are not used anywhere.  The 
const_0_operand is one small typo away from const0_operand.  And as it turns out 
unnecessary for its only use in a define_expand for ctrap. const0_operand is the 
right predicate there anyway.

	* config/nvptx/nvptx.md (const_0_operand, global_mem_operand,
	const_mem_operand, param_mem_operand, shared_mem_operand): Delete.
	(ctrap<mode>): Use const0_operand.
