[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. Patch by Liu Yaxun (Sam)!

[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)!
