or -std=clc++/-std=CLC++.
This aligns with OpenCL C conversion and removes ambiguity
with OpenCL C++.

OpenCL spec requires __OPENCL_C_VERSION__ to be defined based on -cl-std option. This patch implements that.
The patch also defines __FAST_RELAXED_MATH__ based on -cl-fast-relaxed-math option.
Also fixed a test using -std=c99 for OpenCL program. Limit allowed language standard of OpenCL to be OpenCL standards.
