For unpadded dimensions, tensor.pad should behave as a view operation, instead it generates dynamic dimensions and a lot of indexing math for unpadded dimensions being tiled. This patch adds optimizations for cases when high = 0. Along with low = 0 optimizations, this optimizes cases where a dimension is unpadded.
