backend: Add LLVM stable version support
support current llvm stable version 3.2
modify cmake file to check the version of llvm provided by system or
configured by LLVM_INSTALL_DIR, and add a macro define in the format
LLVM_<MAJOR><MINOR> according the version, this macro can be used for
llvm version-specific code.
