omp-low.c (lower_omp_target): Set DECL_VALUE_EXPR of new_var even for the non-array case.

* omp-low.c (lower_omp_target) <case USE_DEVICE_PTR>: Set
	DECL_VALUE_EXPR of new_var even for the non-array case.  Look
	through DECL_VALUE_EXPR for expansion.

	* c-c++-common/goacc/use_device-1.c: New test.
