[OpenCL] Use long instead of long long in x86 builtins

Summary: According to C99 standard long long is at least 64 bits in
size. However, OpenCL C defines long long as 128 bit signed
integer. This prevents one to use x86 builtins when compiling OpenCL C
code for x86 targets. The patch changes long long to long for OpenCL
only.
