[PATCH] D59985: Re-fix invalid address space generation for clk_event_t arguments of enqueue_kernel builtin function

[Alexey Sotkin via Phabricator via cfe-commits]

AlexeySotkin added a comment.

Alternative way to fix it is to use `isNullPointerConstant` like we do in `SemaOpenCLBuiltinEnqueueKernel`. So in case we have a zero literal value we can emit `ConstantPointerNull` directly, without `EmitScalarExpr` .
