Enable OpenCL 2.0 only where supported
This allows a single beignet binary to both offer 2.0 where
available, and still work on older hardware.
V2: Default to 1.2 when -cl-std is not set (required by the OpenCL spec,
and also likely to be faster).
V3: Only enable OpenCL 2.0 when llvm version is 39.
V4: Only enable OpenCL 2.0 on x64 host.
V5: Always return 32 as address bits.
