- Implement lowering pass which detects canonical `aten::Int.Tensor` cases and recursively replaces input Value pointers until all 0D tensors have been resolved to their scalar components - Lowering pass is specialized to replacing strictly integer-typed Value pointers and can only trace through aten::mul and aten::floor_divide operators, which are two of the most common cases of use - Lowering pass traverses the graph until one of three base cases are encountered (or an invalid Value type is detected). These cases are `prim::NumToTensor`, `prim::Constant` (0D tensor), or simple integers. It then replaces the child nodes with the integer equivalents of the produced Tensors - Added extensive testing of new capabilities for accuracy, robustness, and functionality

There was a problem hiding this comment.
Refactored to use c10::optional wrapper instead of nullptr + replaced pointer checks with .has_value()
- Edit in favor of `c10::optional` type usage
