Subject: Declare abstract class ArgumentsAdjuster. This abstract interface
 describes a command line argument adjuster, which is responsible for command
 line arguments modification before the arguments are used to run a frontend
 action.

Define class ClangSyntaxOnlyAdjuster implements ArgumentsAdjuster interface.
This class converts input command line arguments to the "syntax check only"
variant.
