fix for problem

when compiling an .cl file with spir as the target using a command like

clang -cc1 -emit-llvm-bc -triple spir64-unknown-unknown -cl-kernel-arg-info
-fno-builtin add.cl

the kernel misses the required "spir_kernel" calling convention specifier

I attached a patch from https://github.com/KhronosGroup/SPIR for the file

llvm/tools/clang/lib/CodeGen/TargetInfo.cpp

that will fix he problem
