[AArch64] Add test for min/max

[Rin]

Summary

This patch adds a test for min/max.

[Rin]

Remove v2i64 test case.

[dmgreen]

It would be good to keep the v2i64 case I think, it is very similar to v1i64.

I'll re add it.

Add v2i64 testcase

[dmgreen]

It's probably good to add them for all the types, even if just for consistency. So for umax/smax/smin too.

[dmgreen]

Otherwise sounds good to me.

Oh, yeah, sorry, my bad. I'll add them right away.
