There is an implicit parallel in define_insn_and_split.  Don't add your
own.  I quote the documentation:

    If the vector has only one element, that element is the template for
    the instruction pattern.  If the vector has multiple elements, then
    the instruction pattern is a @code{parallel} expression containing
    the elements described.
