[PATCH,FORTRAN] Tweak locations around CAF simplify

[Bernhard Reutner-Fischer]

addresses: FIXME: gfc_current_locus is wrong.
by using the locus of the current intrinsic.
Regtests clean, ok for trunk?

gcc/fortran/ChangeLog:

2018-09-20  Bernhard Reutner-Fischer  <al...@gcc.gnu.org>

        * simplify.c (gfc_simplify_failed_or_stopped_images): Use
        current intrinsic where locus.
        (gfc_simplify_get_team): Likewise.
        (gfc_simplify_num_images): Likewise.
        (gfc_simplify_image_status): Likewise.
        (gfc_simplify_this_image): Likewise.
