    i386: Fix VPMOV splitter [PR105993]

    REGNO should not be used with register_operand before reload because
    subregs of registers or even subregs of memory match the predicate.
    The build with RTL checking enabled does not tolerate REGNO with
    non-reg operand.
    The patch splits the splitter into two related splitters and uses
    (match_dup ...) RTXes instead of REGNO comparisons.
