    Always use name from c_interop_kinds_table for -fc-prototypes.

    When a user specified a KIND that was a parameter taking the value
    of an iso_c_binding KIND, the code used the name of that parameter
    to look up the type name.  Corrected by always looking it up in
    the table of C interop kinds (which was previously done for
    non-C-interop types, anyway).

            c_interop_kinds_table to find the correct C type.
