  [mlir][Rewrite] Add support for using an operation with no results as location

Prior to this patch, using an operation without any results as the location would result in the generation of invalid C++ code. It'd try to format using the result values, which would would end up being an empty string for an operation without any.
This patch fixes that issue by instead using getValueAndRangeUse which handles both ranges as well as the case for an op without any results.
