Can clean this up a bit

if self.dtype in [dtype.u8, dtype.i8, dtype.i32, dtype.i64]:

LGTM. I think your PR for where op modifies _Input.py around the example_tensor call. So make sure the bool type change is integrated when you merge.

Overall LGTM, just some minor comments

Changes for random integer caused failure in arange/cos/sin test. I think it unmasked potential issue as all input values were zero.
I will submit separate PR to address it.
