    aarch64: Remove alignment assertions [PR109661]

    The trunk patch for this PR corrected the ABI for enums that have
    a defined underlying type.  We shouldn't change the ABI on the branches
    though, so this patch just removes the assertions that highlighed
    the problem.

    I think the same approach makes sense longer-term: keep the assertions
    at maximum strength in trunk, and in any new branches that get cut.
    Then, if the assertions trip an ABI problem, fix the problem in trunk
    and remove the assertions from active branches.

    The tests are the same as for the trunk version, but with all Wpsabi
    message and expected output checks removed.
