	* c-common.c (get_atomic_generic_size): New.  Find size of generic
	atomic function parameters and do typechecking.
	(add_atomic_size_parameter): New.  Insert size into parameter list.
	(resolve_overloaded_atomic_exchange): Restructure __atomic_exchange to
	either __atomic_exchange_n or external library call.
	(resolve_overloaded_atomic_compare_exchange): Restructure 
	__atomic_compare_exchange to either _n variant or external library call.
	(resolve_overloaded_atomic_load): Restructure __atomic_load to either 
	__atomic_load_n or an external library call.
	(resolve_overloaded_atomic_store): Restructure __atomic_store to either
	__atomic_store_n or an external library call.
	(resolve_overloaded_builtin): Handle 4 generic __atomic calls.

	* c-typeck.c (build_function_call_vec): Don't reprocess __atomic
	parameters.

	* sync-builtin.def (BUILT_IN_ATOMIC_EXCHANGE_N, BUILT_IN_ATOMIC_LOAD_N,
	BUILT_IN_ATOMIC_COMPARE_EXCHANGE_N, BUILT_IN_ATOMIC_STORE_N): Add "_n"
	to the functions real name.
	(BUILT_IN_ATOMIC_EXCHANGE, BUILT_IN_ATOMIC_LOAD,
	BUILT_IN_ATOMIC_COMPARE_EXCHANGE, BUILT_IN_ATOMIC_STORE): New. Add
	generic atomic builtin functions.

	* gcc.dg/atomic-generic-aux.c: New. Provide 4 functional external
	entrypoints for new generic library functions.
	* gcc.dg/atomic-generic.c: New. Test that generic functions produce
	the expected library calls.
	* gcc.dg/atomic-compare-exchange*.c: Replace __atomic_compare_exchange
	with __atomic_compare_exchange_n.  Add generic variations.
	* gcc.dg/atomic-exchange*.c: Replace __atomic_exchange with
	__atomic_exchange_n.  Add generic variations.
	* gcc.dg/atomic-invalid.c: Add _n to renamed functions.
	gcc.dg/atomic-load*.c: Replace __atomic_load with __atomic_load_n.  Add
	generic variations.
	* gcc.dg/atomic-param.c: Add _n to renamed functions.
