    arm: Fix some more vec-common.md patterns for iwmmxt [PR99724]

    The following patch fixes similar issues as in PR98849;
    in older gcc versions, the expanders were present in neon.md guarded
    with TARGET_NEON, but they got moved to vec-common.md and guarded with
    ARM_HAVE_<MODE>_ARITH so that they handle both MVE and Neon.
    The macros are enabled for some modes even for iwmmxt which has some
    vector support for those modes, but only limited.  In particular,
    neither the one_cmpl, nor neg, nor movmisalign patterns are present.
    For some reason I've failed to construct something that ICEs with
    movmisalign, so that is not covered by the testsuite, but both
    one_cmpl and neg ICE.
