Add initial rough support for synthesizing linker options when passed -fopenmp in the link step on Linux. There is probably more tweaking that will need to take place to get good support for linking the relevant libraries on all Linux distributions and/or on other platforms, but this get's the ball moving and allows Clang to build programs which contain OpenMP pragmas that can be safely ignored by a compiler that doesn't implement them, and yet makes direct calls into the OpenMP runtime. llvm-svn: 172715

[OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492) -fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).
