    fortran: Remove premature initialization of a function result's span
    
    Setting just the span in an otherwise uninitialized array descriptor to
    pass to a function that will use the descriptor for its result (thus do
    the initialization) doesn't seem to be useful.
    
    gcc/fortran/ChangeLog:
    
            * trans-array.cc (gfc_conv_expr_descriptor): Remove
            isolated initialization of the span field before passing to
            the function that will do the initialization.
