[PM] Port ArgumentPromotion to the new pass manager.

Details

Summary

Now that the call graph supports efficient replacement of a function and
spurious reference edges, we can port ArgumentPromotion to the new pass
manager very easily.

The old PM-specific bits are sunk into callbacks that the new PM simply
doesn't use. Unlike the old PM, the new PM simply does argument
promotion and afterward does the update to LCG reflecting the promoted
function.

Depends on D29579.

Still I would really like these tests to use FileCheck instead of grep and check more, but I don't think it makes sense holding a review just for that. I would like to see the output to be checked for some tests (inlined), other than that I'm fine with this patch. Thanks!

Can you check the output is the same here? This old test doesn't even check for it.

Sorry, I tried to do this already and just missed some cases. I've addressed all of them now. One test I just deleted because we actually didn't argument promote anything there, but the rest are now FileCheck based. =]

Rebase now that we actually don't have grep testing here.

Confirmed with Davide that this LGTM now on IRC, landing.
