Hello, @joker-eph! What do you think about it? Should we change the assembly format in `.td`?

From:
```
  let assemblyFormat = [{
    $arg attr-dict (`->` type($results)^)?
    custom<SwitchCases>($cases, $caseRegions) `\n`
    `` `default` $defaultRegion
  }];
```
To: 
```
  let assemblyFormat = [{
    $arg attr-dict (`:` type($results)^)?
    custom<SwitchCases>($cases, $caseRegions) `\n`
    `` `default` $defaultRegion
  }];
```
