    fortran: array descriptor: Move scalar type extraction to callers [PR122521]
    
    The function gfc_get_scalar_to_descriptor_type only uses the TREE_TYPE()
    of its first argument.  Make the function take the type directly as
    argument, moving the TREE_TYPE() access to callers.
    
            PR fortran/122521
    
    gcc/fortran/ChangeLog:
    
            * trans-expr.cc (get_scalar_to_descriptor_type): Remove argument
            `scalar'; add argument `scalar_type'.  Replace `TREE_TYPE (scalar)'
            with `scalar_type'.
            (gfc_conv_scalar_to_descriptor, gfc_conv_derived_to_class,
            gfc_conv_class_to_class): Only pass the type as argument in callers.
