Detailed Description
Folds a tensor.cast op into a consuming DestinationStyleOpInterface op if the tensor.cast has source that is more static than the consuming op.
Example:
%1 = tensor.cast %0 : tensor<8x16xf32> to tensor<?x?xf32>
%2 = consumer %1 ... : tensor<?x?xf32> ...
folds into:
%2 = consumer %0 ... : tensor<8x16xf32> ...
TODO: Move the pattern to a proper place, so all other DestinationStyleOp can add the pattern to their canonicalizers.
