/// CompilerInstance - Helper class for managing a single instance of the Clang
/// compiler.
///
/// The CompilerInstance serves two purposes:
///  (1) It manages the various objects which are necessary to run the compiler,
///      for example the preprocessor, the target information, and the AST
///      context.
///  (2) It provides utility routines for constructing and manipulating the
///      common Clang objects.
///
/// The compiler instance generally owns the instance of all the objects that it
/// manages. However, clients can still share objects by manually setting the
/// object and retaking ownership prior to destroying the CompilerInstance.
///
/// The compiler instance is intended to simplify clients, but not to lock them
/// in to the compiler instance for everything. When possible, utility functions
/// come in two forms; a short form that reuses the CompilerInstance objects,
/// and a long form that takes explicit instances of any required objects.
