        * array.c (gfc_find_array_ref): Handle codimensions.
        (gfc_match_array_spec,gfc_match_array_ref): Use gfc_fatal_error.
        * check.c (is_coarray, dim_corank_check, gfc_check_lcobound,
        gfc_check_image_index, gfc_check_this_image, gfc_check_ucobound):
        New functions.
        * gfortran.h (gfc_isym_id): Add GFC_ISYM_IMAGE_INDEX,
        GFC_ISYM_LCOBOUND, GFC_ISYM_THIS_IMAGE,
        GFC_ISYM_UCOBOUND.
        * intrinsic.h (add_functions): Add this_image, image_index,
        lcobound and ucobound intrinsics.

        gfc_check_image_index, gfc_check_this_image,
        gfc_simplify_image_index, gfc_simplify_lcobound,
        gfc_simplify_this_image, gfc_simplify_ucobound):
        New function prototypes.
        * intrinsic.texi (IMAGE_INDEX, LCOBOUND, THIS_IMAGE
        IMAGE_INDEX): Document new intrinsic functions.
        * match.c (gfc_match_critical, sync_statement): Make
        * -fcoarray=none
        error fatal.
        * simplify.c (simplify_bound_dim): Handle coarrays.
        (simplify_bound): Update simplify_bound_dim call.
        (gfc_simplify_num_images): Add -fcoarray=none check.
