OpenCL C++ part looks good. Thanks!



================
Comment at: test/Headers/opencl-c-header.cl:57-65
 char f(char x) {
-#if __OPENCL_C_VERSION__ != CL_VERSION_2_0
+#if !defined(__OPENCL_CPP_VERSION__) && (__OPENCL_C_VERSION__ != 
CL_VERSION_2_0)
   return convert_char_rte(x);
 
 #else //__OPENCL_C_VERSION__
   ndrange_t t;
   return ctz(x);
----------------
This test looks strange.
It checks that convert_char_rte is compiled if OpenCL version is not 2.0, but 
AFAIK it's not deprecated in OpenCL C 2.0, so I don't know why test is written 
in this way (i.e. ifdef-else-endif).

I think checks should look like this:
```
char f(char x) {
// Check check OpenCL C 2.0 and OpenCL C++ functionality 
#if defined(__OPENCL_CPP_VERSION__) || (__OPENCL_C_VERSION__ == CL_VERSION_2_0)
  ndrange_t t;
  x = ctz(x);
#endif
  return convert_char_rte(x);
}
```

Probably it's better to fix separately.
