z_Linux_asm.s can use the KMP_OS_* / KMP_MIC macros instead of the predefined
compiler macro checks.  The macro logic to determine KMP_MIC is moved from
kmp_os.h to kmp_platform.h.

The CMAKE_OSX_ARCHITECTURES CMake variable allows users to build
universal fat libraries that contain both i386 and x86_64 code.  These
changes allow this build by having the z_Linux_asm.s file detect the architecture
itself instead of receiving it through the build system.

Also, there was a LIBOMP_OSX_ARCHITECTURES CMake variable added to allow
people to only build libomp as a fat library and not the entire LLVM/Clang system.
