[llvm] r194453 - llvm-cov: Added call to update run/program counts.

[Yuchen Wu]

Sorry about that, I was about to check-in the compiler-rt change that includes llvm_gcda_summary_info, but then a previous commit broke the buildbot so I got sidetracked. I didn't see any further build failures, so I thought it was okay leaving this commit in.

I've since committed the compiler-rt changes in r194499. Please let me know if anything else is broken.
