Optimize local_fill_sink

fix shape mismatch in GpuDnnPoolGrad

Implement GpuAdvancedSubtensor1 for gpuarray

elemwise opt

Scan inplace opt

 - it is caused by modification of theano.config.experimental.local_alloc_elemwise_assert in T_local_switch_sink

computer, add one line in the test case to try
to know what happened when it fails

Use shape_of instead of explicitly inserting Shape_i

d3viz: Interactive visualization of Theano compute graphs

Add a 'name' argument to '.copy' method of Theano variables

These Shape_i nodes will not always be optimized away otherwise, and
they prevent local_shape_to_shape_i from being applied.
Instead, we manually apply the equivalent of local_shape_to_shape_i,
by using shape_of[...] directly.
