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.
