* gimplify.c (gimple_add_tmp_var): In SIMD contexts, turn addressable
new vars into GOVD_PRIVATE rather than GOVD_LOCAL.
(gimplify_omp_for): Don't do C++ random access iterator clause
adjustments on combined constructs from OMP_LOOP. For OMP_LOOP,
don't predetermine the artificial iterator in case of C++ random
access iterators as lastprivate, but private. For OMP_LOOP, force
bind expr around simd body and force for_pre_body before the
construct. Use OMP_CLAUSE_LASTPRIVATE_LOOP_IV instead of
OMP_CLAUSE_LASTPRIVATE_TASKLOOP_IV.
(gimplify_omp_loop): Add firstprivate clauses on OMP_PARALLEL for
diff var of C++ random access iterators. Handle
OMP_CLAUSE_FIRSTPRIVATE. For OMP_CLAUSE_LASTPRIVATE_LOOP_IV, if
