@theRealAph Thanks for the review.

@pfustc @DamonFool Thank you for looking into this.
I see some aarch64 files created recently include Oracle copyright, e.g. `aarch64_sve.ad`.
And when I wrote the test code, I did take some files with Oracle copyright as references. 
I think the Oracle copyright statements in testcode should be kept there.
