Anastasia Stulova 1202de3ec8 [OpenCL] Disable C99 standard lib functions 
The library functions defined in the C99 standard headers
are not available (OpenCL v1.2 s6.9.f). 

This change stops treating OpenCL builtin functions as standard C lib
functions to eliminate warning messages about printf format string.

Patch by Liu Yaxun (Sam)!

Anastasia Stulova b607e0f238 [OpenCL] Eliminate warning when declaring OpenCL builtin functions. 
OpenCL builtin functions are usually declared in header files.
Currently clang emits warning for OpenCL builtin functions
which have the same name as standard C library functions.

This commit eliminates such warnings by not adding the C standard
includes following the restriction from OpenCL v1.2 s6.9.f.
