This looks good to me. I do however not have commit rights which means I can't give an official approval. I did encounter the issue this patch fixes when testing the changes in http://reviews.llvm.org/D11877.

A suggestion for a follow-up patch is to rename "ExecGraphViewer" since it's used both for generation and viewing of the graph which can be a bit confusing.
