WIP:Speeding up GpuAdvancedIncSubTensor1 by writing fast Cuda Code

Add utt.assert_allclose that raise a more informative error.

This is needed in the Scan tests.

The numpy.allclose() use a tolerate too high for float32.

This will help remove an error that appear with different seed in the tests.

Fix tests

Rebase gh-1368

fix for variable size array problem in Windows compiler

[WIP] Use the new grad interface.

This print the time used for each batch.

The old range was causing nan in float32.

When the output was of size 0, we where returning a numpy ndarray
instead of a CudaNdarray.

No news, as this is a fix to something new since the last release.

Make GpuCrossentropySoftmaxArgmax1HotWithBias and GpuCrossentropySoftmax1HotWithBiasDx work for bigger inputs.

I don't know if argsort should have a grad defined, so I mark it as not implemented.

Fix opt crash of local_gpu_lazy_ifelse.

Also print the inputs type.

exception_verbosity now only add the debugprint that now also have the print_type parameter

Fix GpuConv error reporting. The error was raised in the next executed apply node when we detect the input to be None instead of CudaNdarray.

this fixes gh-786.

It was passing event if it tested the wrong stuff. After fixing it
still work correctly.

It was a set, not it is now a list. This cause problem in the error handling code where we try to get the index in a set. That isn't defined.
