Hi Nils,

thank you for the feedback!

No, I have not, because there is an existing issue (INTJDK-7620326) that 
is supposed to take care of the high execution time of intrinsic-related 
tests on platforms where the relevant intrinsics are not available. I've 
linked the two issues.

You are right, they are in part new (in part old intrinsics have been 
updated). I thought to remove them nevertheless, because they take a 
long time to execute and are anyway executed in our nightlies.

Best regards,
