      Umbrella issue for tasks associated with integration of the third incubation of the Vector API.

      Sub-task 1 will be integrated independently of other sub-tasks.

      Sub-task 2 to 5 (related to mask supported) will be integrated under one PR, although it may be possible for ease of review to separate the relevant code changes.
      The changes for these sub-tasks can currently be viewed from https://github.com/openjdk/panama-vector/tree/vectorIntrinsics and the vectorIntrinsics branch will be used to create the PR that updated in response to review comments.

      Sub-tasks 1 to 5 require no specific CSRs, but some minor API fixes might be identified. Any such API updates will use a CSR associated with this issue.

      Future sub-tasks, to be integrated independently, may be added for Vector API enhancements, which will require CSRs.

      The JEP will be marked as integrated once all sub-tasks have been completed.
