JFTR, I think this was a case when we were using builtins for
implementation of the ACLE intrinsics and the testcase was reduced to
remove the use of arm_neon.h . Thus the test needs to go back to using
the neon intrinsics directly if possible.

Also if there are other tests like this it would be a good small cleanup
to do.

Indeed but that's a separate issue to this.
