Runtime Shared Library compilation and testing (#985)

* Removed the need for VisualStudio specific CPPCompiler
Improved the version parsing for gcc/clang
Removed need for slang-unix-cpp-compiler-util.cpp/.h
Remove binary before compiling in the compile c tests

* Moved VisualStudio calcArgs into CPPCompilerUtil - as code is not windows specific.

* Set up compile time version for gcc and clang

* Fix compilation on OSX - use remove instead of unlink for file deletion.

* On OSX - clang uses different string format.

* Removed /bin/sh invoking as not required for OSX.

* First pass working testing with shared libraries.
