* When `step` is 1 and either `start` or `stop` is a boundary, the
  canonical representation of `slice(start, stop, step)` is now simpler

* Other simplifications in the more general case when `step` is a
  constant

* Fixed crash when calling `get_scalar_constant_value()` on a numpy
  array.

* Ensure that start <= stop in canonical slice representations, which
  makes it easier to compute their length.

Fix ConstructSparseFromList.infer_shape

Now, the first argument contains the shape itself, so we should use
its value, not its shape.

Fixes

Add assert in make_node

fix bug reported by Nicolas

Fix bug in erfinv GPU optimization

Check Python long are OK iff they fit in int64

make erfinv work on the gpu.

Add export for GPU code on windows.

Enable long ints in reshape

Update the conv2d doc to hopefully make it more clear.

Allow Python long integers in indexing.

inv_as_solve optimization checks if op is Dot

Advinc rebase3

Previously it checked if node.op == dot where dot was a dot function
I assume that this was a mistake

I've changed this to check if isinstance(node.op, (Dot, Dot22))
I've also added a test

Initial version of the compatibility guide.
