re PR fortran/70598 (Fortran OpenACC host_data construct ICE) 

2016-08-14  Chung-Lin Tang  <cltang@codesourcery.com>

	PR fortran/70598

	gcc/fortran/
	* openmp.c (resolve_omp_clauses): Adjust use_device clause
	handling to only allow pointers and arrays.

	gcc/testsuite/
	* gfortran.dg/goacc/host_data-tree.f95: Adjust to use pointers
	in use_device clause.
	* gfortran.dg/goacc/uninit-use-device-clause.f95: Likewise.
	* gfortran.dg/goacc/list.f95: Adjust to catch
	"neither a POINTER nor an array" error messages.

	libgomp/
	* testsuite/libgomp.oacc-fortran/host_data-1.f90: New test.
