Driver: bifurcate extended and basic MSC versioning
This restores the original behaviour of -fmsc-version. The older option remains as a mechanism for specifying the basic version information. A secondary option, -fms-compatibility-version permits the user to specify an extended version to the driver. The new version takes the value as a dot-separated value rather than the major * 100 + minor format that -fmsc-version format. This makes it easier to specify the value as well as a more flexible manner for specifying the value. Specifying both values is considered an error. The older parameter is left solely as a driver option, which is normalised into the newer parameter. This allows us to retain a single code path in the compiler itself whilst preserving the semantics of the old parameter as well as avoid having to determine which of two formats are being used by the invocation. The test changes are due to the fact that the compiler no longer supports the old option, and is a direct conversion to the new option. llvm-svn: 213119
