@kgryte can you please remove #2464 to be closed from completion of this PR, github is not allowing me to do that.
Edit: done automatically by changing resolves to towards, sorry for unnecessary ping.
I'll add more tests once decision over #2792 is made. Now, working to support negative strides for idamax.
