LLVM tools print installation path upon execution. If one uses LLVM
tools bundled with Microsoft Visual Studio installation, they would be
incorrectly detected as Microsoft's ones.
Microsoft tools can have localized names, so a more specific string
check is not feasible, but luckily we can test if "Microsoft" is at the
beginning of the line, as it is always the case.
