Routine Description:

    This routine dumps the virtual PIC state.

Arguments:

    CurrentProcess -- Supplies a handle to the process to dump selectors for
    CurrentThread -- Supplies a handle to the thread to dump selectors for
    ArgumentString -- Supplies the arguments to the !sel command

Return Value

    None.
