bug: The optimization where converting the ignore_border=False to ignore_border=True.

crash: The optimization that convert the gpudownsample grad to
cuddpoolgrad was swapping the inputs parameter. This is caused in part
by cudnn using strange definition of input and output. Now the op use
the same inputs order as the other pool grad ops. The only difference
is tha the c_code() use the name that cudnn use. There is a comment
that tell that.

This just remove warning and to not implement the case where the

Allow opt registered in name EquilibriumDB to do not be enable by the EquilibrumDB name and use that for local_remove_all_assert opt.
