[Beignet] [PATCH 1/2] Fix a build problem when the llvm version has the fix version digit.

[Zhigang Gong]

If the llvm version is something like 3.3.1, the previous cmake script
will generate an incorrect cflags as: -DLLVM_33 1 which breaks the build.

This commit also update the stable llvm version from 3.1 to 3.3.
