[bader]

@alexbatashev, @vladimirlaz, these issues impact post-commit testing. Could you take a look ASAP, please?

[alexbatashev]

@bader for the first bug the fix should be trivial. For the second, I don't see how the first failed commit is related to the failure. It looks like the latest llvm contains some kind of bug, so self build fails with ICE.
