Template symbols produced by MWCC diff incorrectly

split_off_address handles instructions with address immediates (generally branch instructions). The line is split by a comma in split_off_address. We want the entire address/symbol to be diffed for highlighting rather than just a part of it.

def split_off_address(line: str) -> Tuple[str, str]:
    """Split e.g. 'beqz $r0,1f0' into 'beqz $r0,' and '1f0'."""
    parts = line.split(",")
    if len(parts) < 2:
        parts = line.split(None, 1)
        if len(parts) < 2:
            parts.append("")
    off = len(line) - len(parts[-1].strip())
    return line[:off], line[off:]

This image shows that when the first part of the template split by the comma differs, the line is not highlighted.

When the 2nd part of the template differs (split_off_address):
