Adds a new pass, `splitlarge`, that recursively divides $add/$sub cells into smaller cells until each cell's width doesn't exceed a given max_width (128 by default.) An $add/$sub cell's width for this purpose is defined as the higher of the widths of its two inputs. A test was written in Tcl for it, which tests this matrix: - cell: $add/$sub - b: unsigned, signed - a: unsigned, signed This is the first test for a Silimate pass in Tcl and thus `run-test.sh` was modified to include it.
