    fortran: array descriptor: Rename internal field accessor for span [PR122521]
    
    Make the internal accessor for span respect the convention that static
    functions don't have the `gfc_' prefix.
    
            PR fortran/122521
    
    gcc/fortran/ChangeLog:
    
            * trans-descriptor.cc (gfc_conv_descriptor_span): Rename ...
            (conv_descriptor_span): ... to this.
            (gfc_conv_descriptor_span_get, gfc_conv_descriptor_span_set): Update
            callers.
