OpenCL disallows using variadic arguments (s6.9.e and s6.12.5 OpenCL v2.0) apart from some exceptions: - printf - enqueue_kernel This change adds error diagnostic for variadic functions but accepts printf and any compiler internal function (which should cover __enqueue_kernel_XXX cases). It also unifies diagnostic with block prototype and adds missing uncaught cases for blocks. llvm-svn: 285395
