[Beignet] [PATCH v3] disable overflow utest test before llvm-3.5

[xionghu.luo at intel.com]

From: Luo Xionghu <xionghu.luo at intel.com>

the overflow intrinsics are introduced since llvm-3.5.

v2: no need to exclude bswap test since llvm-3.3 supports it.

v3: disable the overflow utest in cmake instead of code.
