Message:

score: Remove _ISR_Dispatch()

This function was only used on some m68k variants. On these m68k
variants there is no need to use a global symbol. Use a local label
instead.

Remove _ISR_Dispatch() from the architecture-independent layer.

    149  *  @brief ISR wrapper for thread dispatcher.
    150  *
    151  *  This routine provides a wrapper so that the routine
    152  *  @ref _Thread_Dispatch can be invoked when a reschedule is necessary
    153  *  at the end of the outermost interrupt service routine.  This
    154  *  wrapper is necessary to establish the processor context needed
    155  *  by _Thread_Dispatch and to save the processor context which is
    156  *  corrupted by _Thread_Dispatch.  This context typically consists
    157  *  of registers which are not preserved across routine invocations.
    158  *
    159  *  @note  Typically mplemented in assembly language.
