    aarch64: fix strict alignment for vector load/stores (PR 91927)

    Hi,
      The problem here is that the vector mode version of movmisalign<mode>
    was only conditionalized on if SIMD was enabled instead of being
    also conditionalized on STRICT_ALIGNMENT too.

    Applied as pre-approved in the bug report by Richard Sandiford
    after a bootstrap/test on aarch64-linux-gnu.

    Thanks,
    Andrew Pinski

    * config/aarch64/aarch64-simd.md (movmisalign<mode>): Check
    STRICT_ALIGNMENT also.
