    fortran: Set name for *LOC default BACK argument [PR108450]

    This change fixes an ICE caused by the double resolution of MINLOC,
    MAXLOC and FINDLOC expressions which get a default value for the BACK
    argument at resolution time.  That argument  is added without name,
    and argument reordering code is not prepared to handle unnamed arguments
    coming after named ones, so the second resolution causes a NULL pointer
    dereference.
    The problem is fixed by explicitly setting the argument name.
