Don't allow mixed component and non-component accesses for OpenACC/Fortran

	gcc/fortran/
	* gfortran.h (gfc_symbol): Add comp_mark bitfield.
	* openmp.c (resolve_omp_clauses): Disallow mixed component and
	full-derived-type accesses to the same variable within a single
	directive.

	libgomp/
	* testsuite/libgomp.oacc-fortran/deep-copy-2.f90: Remove test from here.
	* testsuite/libgomp.oacc-fortran/deep-copy-3.f90: Don't use mixed
	component/non-component variable refs in a single directive.
	* testsuite/libgomp.oacc-fortran/classtypes-1.f95: Likewise.

	gcc/testsuite/
	* gfortran.dg/goacc/deep-copy-2.f90: Move test here (from libgomp
	testsuite). Make a compilation test, and expect rejection of mixed
	component/non-component accesses.
	* gfortran.dg/goacc/mapping-tests-1.f90: New test.
