Perhaps this (& below) would be more legible following the way `Discriminator` is printed, using an `if` rather than a conditional operator:
```
OS << Filename << ':' << Info.Line << ':' << Info.Column
if (Info.IsApproximatedLine)
  OS << " " << Info.ApproxString;
OS << '\n';
```
(& same change below in `GNUPrinter::printSimpleLocation`)
