http://gerrit.cloudera.org:8080/#/c/9584/1/be/src/codegen/llvm-codegen.cc@288
PS1, Line 288: std::
Is the std:: necessary? (I probably added it, but trying to keep the codebase 
somewhat consistent).

PS1, Line 292:         std::move(err), [&](llvm::ErrorInfoBase& eib) { 
err_string = eib.message(); });
I guess this means that errors are not propagated by the diagnostic handler 
now? This method seems somewhat saner but it's hard to know what the right 
thing to do is with some of these APIs.

Let's make sure we don't forget this :)

Don't we want a space here?
