Fix CO_REDUCE with RESULT_IMAGE.
gcc/fortran/ChangeLog:
* trans-array.c (gfc_conv_ss_descriptor): Use correct ref.
* trans-intrinsic.c (trans_argument): Use gfc_conv_expr_reference.
* trans-decl.c (gfc_build_builtin_function_decls):
Correct spec for array.
libgfortran/ChangeLog:
* caf_shared/collective_subroutine.c (collsub_reduce_array):
Fix off by one error for result.
gcc/testsuite/ChangeLog:
* gfortran.dg/caf-shared/co_reduce_1.f90: New test.
