Backport of #107601to release/9.0

/cc @kunalspathak @SwapnilGaikwad

Customer Impact

  • Customer reported
  • Found internally

The test template logic for *ExtendWidening SVE intrinsics was not calling the correct helper method to verify the intrinsic's return value for an enabled vector lane under ConditionalSelect scenarios. Furthermore, for vector lanes disabled by the mask passed to ConditionalSelect, the test logic was not comparing the element to the expected true/false value. This PR fixes both issues.

Regression

  • Yes
  • No

This was introduced by #107207, which was fixing an actual JIT bug, and added this new test logic to improve coverage.

Testing

With this fix, all of our SVE tests are now passing.

Risk

Low. This fix is only to ensure CI is clean on release/9.0.
