SetFile has an optional style argument which defaulted to the native style. This patch makes that argument mandatory so clients of the FileSpec class are forced to think about the correct syntax. At the same time this introduces a (protected) convenience method to update the file from within the FileSpec class that keeps the current style. These two changes together prevent a potential pitfall where the style might be forgotten, leading to the path being updated and the style unintentionally being changed to the host style. llvm-svn: 334663
