Daniel Dunbar c1b1729b66 Break Frontend's dependency on Rewrite, Checker and CodeGen in shared library configuration
Currently, all AST consumers are located in the Frontend library,
meaning that in a shared library configuration, Frontend has a
dependency on Rewrite, Checker and CodeGen.  This is suboptimal for
clients which only wish to make use of the frontend.  CodeGen in
particular introduces a large number of unwanted dependencies.

This patch breaks the dependency by moving all AST consumers with
dependencies on Rewrite, Checker and/or CodeGen to their respective
libraries.  The patch therefore introduces dependencies in the other
direction (i.e. from Rewrite, Checker and CodeGen to Frontend).

After applying this patch, Clang builds correctly using CMake and
shared libraries ("cmake -DBUILD_SHARED_LIBS=ON").

N.B. This patch includes file renames which are indicated in the
patch body.

Changes in this revision of the patch:
 - Fixed some copy-paste mistakes in the header files
 - Modified certain aspects of the coding to comply with the LLVM
   Coding Standards

This is an example of Clang based interpreter, for executing standalone C
programs.

It demonstrates the following features:
 1. Parsing standard compiler command line arguments using the Driver library.

 2. Constructing a Clang compiler instance, using the appropriate arguments
    derived in step #1.

 3. Invoking the Clang compiler to lex, parse, syntax check, and then generate
    LLVM code.

 4. Use the LLVM JIT functionality to execute the final module.

The implementation has many limitations and is not designed to be a full fledged
C interpreter. It is designed to demonstrate a simple but functional use of the
Clang compiler libraries.
