Slang -> C++ -> SharedLibrary -> Test (#999)

* WIP: Adding support for C/C++ compilation to slang API.

* Removed BackEndType in test harness -> use SlangPassThrough to identify backends
Only require stage for targets that require it.
Detection of all different backends.

* Windows/Unix create temporary filename.

* WIP: Output CPU binaries.

* Added a pass-through c/c++ test.

* Compile C++/C and store in temporary file.

* Read the binary back into memory.

* Set debug info and optimization flags for C/C++.
Make the CPPCompiler debug/optimization levels match slangs.

* Handling of include paths and math precision.

* Dumping c++/c source and exe/shared library.

* Put hex dump into own util.

* End to end pass through c compilation test.

* WIP: Simple execute test working on Linux/Unix.

* Fix typo on linux.

* WIP: To compile slang to cpp shared library. Report backend compiler errors.

* Compiles slang -> cpp and loads as shared library.

* Fix problem on c-cross-compile test because prelude is now included with <> quotes.

* Run slang generated cpp code - using hard coded data.

* Added cpp-execute-simple, and test output.

* Fix warning that broke win32 build.

* Fix compilation problem on osx.
