Expand clang-interpreter with example of throwing in and from the JIT for Windows64. Summary: Getting this to work is not particularly obvious, and having it as an example should be helpful. Portions of this could be placed into LLVM, but as a whole it seems necessary to do this a higher level.

This is an example of Clang based interpreter, for executing standalone C/C++
Add a minimal C interpreter example. - Demonstrates how to build a standalone tool which loads source code using the Driver and Frontend libraries, and then uses CodeGen and the JIT to actually execute the code. - Still more complicated than it should be, but hey its only 153 lines. :) -- ddunbar@ozzy:tmp$ cat hello.c #include <stdio.h> int main() { printf("hello world\n"); return 0; } ddunbar@ozzy:tmp$ clang-interpreter hello.c hello world -- llvm-svn: 97133

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.
clang-interpreter: use LLVM interpreter if JIT is unavailable Update the strategy in r212083 to try JIT first and otherwise fall back to the interpreter. This gives the best of both worlds and still builds fine with no targets enabled. Requires supporting changes from LLVM r212086. llvm-svn: 212087

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