fix gh-1133, don't replace error message from compute_test_value.
fix comment following code review.
better fix to gh-1133. This do not change the interface to make_node in case of error.
Make check_blas.py print more information.
fix garray_to_cudandarray for dimensions of 0. CudaNdarray need a strides of 0 in those cases, not 1. Error was raised in filter about this.
Inherit from the right exception to stay compatible with old code.
