Antonio Sanchez d82d915047 Modify tensor argmin/argmax to always return first occurence.
As written, depending on multithreading/gpu, the returned index from
`argmin`/`argmax` is not currently stable.  Here we modify the functors
to always keep the first occurence (i.e. if the value is equal to the
current min/max, then keep the one with the smallest index).

This is otherwise causing unpredictable results in some TF tests.
