* gimplify.c (find_combined_omp_for): Add DATA argument, in addition
to finding the inner OMP_FOR/OMP_SIMD stmt find non-trivial wrappers,
BLOCKs with BLOCK_VARs, OMP_PARALLEL in between, OMP_FOR in between.
(gimplify_omp_for): For composite loops, move outer
OMP_{DISTRIBUTE,TASKLOOP,FOR,PARALLEL} right around innermost
OMP_FOR/OMP_SIMD if there are any non-trivial wrappers. For class
iterators add any needed clauses. Allow OMP_FOR_ORIG_DECLS to contain
TREE_LIST for both the original class iterator and the "last" helper
var. Gimplify OMP_FOR_PRE_BODY before the outermost composite
loop, remember has_decl_expr from outer composite loops for the
innermost OMP_SIMD in TREE_PRIVATE bit on OMP_FOR_INIT.

* c-omp.c (c_omp_check_loop_iv_r, c_omp_check_loop_iv): Allow declv
to contain TREE_LIST for both the original class iterator and the
"last" helper var.
gcc/cp/
* semantics.c (handle_omp_for_class_iterator): Remove lastp argument,
instead of setting *lastp turn orig_declv elt into a TREE_LIST.
(finish_omp_for): Adjust handle_omp_for_class_iterator caller.
* pt.c (tsubst_omp_for_iterator): Allow OMP_FOR_ORIG_DECLS to contain
TREE_LIST for both the original class iterator and the "last" helper
var.

* testsuite/libgomp.c++/for-15.C: New test.
