	* builtins.c (expand_builtin): Remove 4th parameter representing 
	weak/strong mode when __atomic_compare_exchange becomes a library call.

	* gcc.dg/atomic-generic-aux.c (__atomic_compare_exchange): Fail if 
	memory model parameters don't match expected values.
	* gcc.dg/atomic-generic.c: Pass specific memory model parameters to
	__atomic_compare_exchange.
	* gcc.dg/atomic-noinline.c: Pass specific memory model parameters to
	__atomic_compare_exchange_n.
	* gcc.dg/atomic-noinline-aux.c (__atomic_compare_exchange_2): Remove
	weak/strong parameter and fail if memory models aren't correct.
