Some makefiles created for testing openmp. - `makefiles/Makefile.homebrewllvm` - `Makefiles/Makefile.testmachomebrew`

Generating dylib successfully done, with `makefiles/Makefile.homebrewllvm` with `make dylib`. homebrew llvm doesn't support multi-architecture, Cannot use multiple `-arch` parameters for universal binary.

homebrew llvm dylib + macOS native llvm-gcc linking successfully worked.

Performance extremely increased for butterfly.png on my old MacBook Pro Ratina 13" (2015) CTO, Intel(R) Core(TM) i7-5557U CPU @ 3.10GHz. ``` > bin/srcnntest Pictures/butterfly.png --scale=2 - Loading image : Pictures/butterfly.png...

## Conclusion * openMP makes 10 times better performance on old-generaiton Mac systems, specially Intel CPUs.
