Yibo Cai created ARROW-13944:
--------------------------------

             Summary: [C++] Bump xsimd to latest version
                 Key: ARROW-13944
                 URL: https://issues.apache.org/jira/browse/ARROW-13944
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Yibo Cai
            Assignee: Yibo Cai


xsimd is refactored to use architecture instead of register size to define a batch.
I've adapted arrow code to this change.
There's one xsimd bug [1] needs to fix before we can upgrade.
