Quick FusedBatchNorm performance regression fix:
When not compiled with "--config=opt", or when compiling with "--config=opt --distinct_host_configuration=false" (to skip host-specific optimizations), the following code incurs casting overhead even when T == U,
y.reshape(rest_by_depth).device(d) = x_shifted.template cast<T>();
The fix: explicitly avoid calling cast<T>() if T == U.
