count.
Add tests for vec_signextq.
* gcc.target/powerpc/p9-sign_extend-runnable.c: New test case.
Looking at the GCC 11 tree it looks like I did backport and commit it there as
well:

Probably should have fixed the commit log date.
So, it looks to me like this has been done and the issue should be closed.
