So I know this is how clang-format formats these, but that’s not how we want
them to be formatted unfortunately... so can you instead reformat them to be
like the other diagnostics. E.g. instead of
```td
def err_unsupported_itanium_expr_mangling
: Error<"cannot yet mangle %0 expression">;
```
do
```td
def err_unsupported_itanium_expr_mangling : Error<
"cannot yet mangle %0 expression">;
```
